The Apache Commons Codec package contains simple encoder and decoders for
various formats such as Base64 and Hexadecimal. In addition to these
widely used encoders and decoders, the codec package also maintains a
collection of phonetic encoding utilities.
The newest version!

Apache XMLBean changes:
2006/01/25: Updated to be consistent with the schema at
http://www.w3.org/2001/XMLSchema.xsd as of this date with the exception that
the modifications in the previous version of this file to the regular
expressions that describe the integrity constraint xpaths (which permit
whitespaces in certain places which would not otherwise be allowed)
have been retained in this copy as in the previous version of this file.
The schema corresponding to this document is normative,
with respect to the syntactic constraints it expresses in the
XML Schema language. The documentation (within <documentation> elements)
below, is not normative, but rather highlights important aspects of
the W3C Recommendation of which this is a part
The simpleType element and all of its members are defined
towards the end of this schema document
Get access to the xml: attribute groups for xml:lang
as declared on 'schema' and 'documentation' below
This type is extended by almost all schema types
to allow attributes from other namespaces to be
added to user schemas.
This type is extended by all types which allow annotation
other than <schema> itself
This group is for the
elements which occur freely at the top level of schemas.
All of their types are based on the "annotated" type by extension.
This group is for the
elements which can self-redefine (see <redefine> below).

#all or (possibly empty) subset of {substitution, extension,

The element element can be used either
at the top level to define an element-type binding globally,
or within a content model to either reference a globally-defined
element or type or declare an element-type binding locally.
The ref form is not allowed at the top level.

group references

simple type for the value of the 'namespace' attr of
'any' and 'anyAttribute'
Value is
##any - - any non-conflicting WFXML/attribute at all
##other - - any non-conflicting WFXML/attribute from
namespace other than targetNS
##local - - any unqualified non-conflicting WFXML/attribute

more URI the listed namespaces

(space separated)
##targetNamespace or ##local may appear in the above list, to
refer to the targetNamespace of the enclosing
schema or an absent targetNamespace respectively
A utility type, not for public use
A subset of XPath expressions for use
in selectors
A utility type, not for public
use
The following pattern is intended to allow XPath
expressions per the following EBNF:
Selector ::= Path ( '|' Path )*
Path ::= ('.//')? Step ( '/' Step )*
Step ::= '.' | NameTest
NameTest ::= QName | '*' | NCName ':' '*'
child:: is also allowed
A subset of XPath expressions for use
in fields
A utility type, not for public
use
The following pattern is intended to allow XPath
expressions per the same EBNF as for selector,
with the following change:
Path ::= ('.//')? ( Step '/' )* ( Step | '@' NameTest )
The three kinds of identity constraints, all with
type of or derived from 'keybase'.
A utility type, not for public use
A public identifier, per ISO 8879
notations for use within XML Schema schemas
Not the real urType, but as close an approximation as we can
get in the XML representation
First the built-in primitive datatypes. These definitions are for
information only, the real built-in definitions are magic.
For each built-in datatype in this schema (both primitive and
derived) can be uniquely addressed via a URI constructed
as follows:
1) the base URI is the URI of the XML Schema namespace
2) the fragment identifier is the name of the datatype
For example, to address the int datatype, the URI is:
http://www.w3.org/2001/XMLSchema#int
Additionally, each facet definition element can be uniquely
addressed via a URI constructed as follows:
1) the base URI is the URI of the XML Schema namespace
2) the fragment identifier is the name of the facet
For example, to address the maxInclusive facet, the URI is:
http://www.w3.org/2001/XMLSchema#maxInclusive
Additionally, each facet usage in a built-in datatype definition
can be uniquely addressed via a URI constructed as follows:
1) the base URI is the URI of the XML Schema namespace
2) the fragment identifier is the name of the datatype, followed
by a period (".") followed by the name of the facet
For example, to address the usage of the maxInclusive facet in
the definition of int, the URI is:
http://www.w3.org/2001/XMLSchema#int.maxInclusive
NOTATION cannot be used directly in a schema; rather a type
must be derived from it by specifying at least one enumeration
facet whose value is the name of a NOTATION declared in the
schema.
Now the derived primitive types
pattern specifies the content of section 2.12 of XML 1.0e2
and RFC 3066 (Revised version of RFC 1766).

#all or (possibly empty) subset of {restriction, union, list}
A utility type, not for public use
Can be restricted to required or forbidden
Required at the top level
Forbidden when nested
We should use a substitution group for facets, but
that's ruled out because it would allow users to
add their own, which we're not ready for yet.
base attribute and simpleType child are mutually
exclusive, but one or other is required
itemType attribute and simpleType child are mutually
exclusive, but one or other is required
memberTypes attribute must be non-empty or there must be
at least one simpleType child
