This XML Schema Document encodes various parameters and
parameter types that can be used in OWS operation requests and responses.
OWS is an OGC Standard.

XML encoded identifier of a standard MIME type, possibly
a parameterized MIME type.
Specification version for OWS operation. The string value
shall contain one x.y.z "version" value (e.g., "2.1.3"). A version
number shall contain three non-negative integers separated by decimal
points, in the form "x.y.z". The integers y and z shall not exceed 99.
Each version shall be for the Implementation Specification (document)
and the associated XML Schemas to which requested operations will
conform. An Implementation Specification version normally specifies XML
Schemas against which an XML encoded operation response must conform and
should be validated. See Version negotiation subclause for more
information.
This element either references or contains more metadata
about the element that includes this element. To reference metadata
stored remotely, at least the xlinks:href attribute in xlink:simpleLink
shall be included. Either at least one of the attributes in
xlink:simpleLink or a substitute for the AbstractMetaData element shall
be included, but not both. An Implementation Specification can restrict
the contents of this element to always be a reference or always contain
metadata. (Informative: This element was adapted from the
metaDataProperty element in GML 3.0.)
Reference to metadata recorded elsewhere, either
external to this XML document or within it. Whenever practical, the
xlink:href attribute with type anyURI should include a URL from which
this metadata can be electronically retrieved.
Optional reference to the aspect of the element which
includes this "metadata" element that this metadata provides more
information about.
Abstract element containing more metadata about the
element that includes the containing "metadata" element. A specific
server implementation, or an Implementation Specification, can define
concrete elements in the AbstractMetaData substitution
group.
XML encoded minimum rectangular bounding box (or region)
parameter, surrounding all the associated data.
This type is adapted from the EnvelopeType of GML 3.1,
with modified contents and documentation for encoding a MINIMUM size box
SURROUNDING all associated data.
Position of the bounding box corner at which the
value of each coordinate normally is the algebraic minimum within
this bounding box. In some cases, this position is normally
displayed at the top, such as the top left for some image
coordinates. For more information, see Subclauses 10.2.5 and
C.13.
Position of the bounding box corner at which the
value of each coordinate normally is the algebraic maximum within
this bounding box. In some cases, this position is normally
displayed at the bottom, such as the bottom right for some image
coordinates. For more information, see Subclauses 10.2.5 and
C.13.
Usually references the definition of a CRS, as
specified in [OGC Topic 2]. Such a CRS definition can be XML encoded
using the gml:CoordinateReferenceSystemType in [GML 3.1]. For well
known references, it is not required that a CRS definition exist at
the location the URI points to. If no anyURI value is included, the
applicable CRS must be either: a) Specified outside the bounding box,
but inside a data structure that includes this bounding box, as
specified for a specific OWS use of this bounding box type. b) Fixed
and specified in the Implementation Specification for a specific OWS
use of the bounding box type.
The number of dimensions in this CRS (the length of a
coordinate sequence in this use of the PositionType). This number is
specified by the CRS definition, but can also be specified
here.
Position instances hold the coordinates of a position in
a coordinate reference system (CRS) referenced by the related "crs"
attribute or elsewhere. For an angular coordinate axis that is
physically continuous for multiple revolutions, but whose recorded
values can be discontinuous, special conditions apply when the bounding
box is continuous across the value discontinuity: a) If the bounding box
is continuous clear around this angular axis, then ordinate values of
minus and plus infinity shall be used. b) If the bounding box is
continuous across the value discontinuity but is not continuous clear
around this angular axis, then some non-normal value can be used if
specified for a specific OWS use of the BoundingBoxType. For more
information, see Subclauses 10.2.5 and C.13.
This type is adapted from DirectPositionType and
doubleList of GML 3.1. The adaptations include omission of all the
attributes, since the needed information is included in the
BoundingBoxType.
XML encoded minimum rectangular bounding box (or region)
parameter, surrounding all the associated data. This box is specialized
for use with the 2D WGS 84 coordinate reference system with decimal
values of longitude and latitude.
This type is adapted from the general BoundingBoxType,
with modified contents and documentation for use with the 2D WGS 84
coordinate reference system.
Position of the bounding box corner at which the
values of longitude and latitude normally are the algebraic
minimums within this bounding box. For more information, see
Subclauses 10.4.5 and C.13.
Position of the bounding box corner at which the
values of longitude and latitude normally are the algebraic
minimums within this bounding box. For more information, see
Subclauses 10.4.5 and C.13.
This attribute can be included when considered
useful. When included, this attribute shall reference the 2D WGS
84 coordinate reference system with longitude before latitude and
decimal values of longitude and latitude.
The number of dimensions in this CRS (the length of
a coordinate sequence in this use of the PositionType). This
number is specified by the CRS definition, but can also be
specified here.
Two-dimensional position instances hold the longitude and
latitude coordinates of a position in the 2D WGS 84 coordinate reference
system. The longitude value shall be listed first, followed by the
latitude value, both in decimal degrees. Latitude values shall range
from -90 to +90 degrees, and longitude values shall normally range from
-180 to +180 degrees. For the longitude axis, special conditions apply
when the bounding box is continuous across the +/- 180 degrees meridian
longitude value discontinuity: a) If the bounding box is continuous
clear around the Earth, then longitude values of minus and plus infinity
shall be used. b) If the bounding box is continuous across the value
discontinuity but is not continuous clear around the Earth, then some
non-normal value can be used if specified for a specific OWS use of the
WGS84BoundingBoxType. For more information, see Subclauses 10.4.5 and
C.13.
