/**
* Maps a package name to a XML namespace.
*
* Usage
*
* The XmlSchema annotation can be used with the following program
* elements:
*
* - package
*
*
*
* This is a package level annotation and follows the recommendations
* and restrictions contained in JSR 175, section III, "Annotations".
* Thus the usage is subject to the following constraints and
* recommendations.
*
* - There can only be one package declaration as noted in JSR
* 175, section III, "Annotations".
* - JSR 175 recommends package-info.java for package level
* annotations. JAXB Providers that follow this recommendation
* will allow the package level annotations to be defined in
* package-info.java.
*
*
* Example 1: Customize name of XML namespace to which
* package is mapped.
*
*
* @javax.xml.bind.annotation.XmlSchema (
* namespace = "http://www.example.com/MYPO1"
* )
* {@code
*
*
*
*
* }
*
* Example 2: Customize namespace prefix, namespace URI
* mapping
*
*
* // Package level annotation
* @javax.xml.bind.annotation.XmlSchema (
* xmlns = {
* @javax.xml.bind.annotation.XmlNs(prefix = "po",
* namespaceURI="http://www.example.com/myPO1"),
*
* @javax.xml.bind.annotation.XmlNs(prefix="xs",
* namespaceURI="http://www.w3.org/2001/XMLSchema")
* }
* )
* {@code
*
*
*
*
* }
*
* Example 3: Customize elementFormDefault
*
* @javax.xml.bind.annotation.XmlSchema (
* elementFormDefault=XmlNsForm.UNQUALIFIED
* ...
* )
* {@code
*
*
*
*
* }
* @author Sekhar Vajjhala, Sun Microsystems, Inc.
* @since 1.6, JAXB 2.0

/**
* Indicates that this namespace (specified by {@link #namespace()})
* has a schema already available exeternally, available at this location.
*
*
* This instructs the JAXB schema generators to simply refer to
* the pointed schema, as opposed to generating components into the schema.
* This schema is assumed to match what would be otherwise produced
* by the schema generator (same element names, same type names...)
*
*
* This feature is intended to be used when a set of the Java classes
* is originally generated from an existing schema, hand-written to
* match externally defined schema, or the generated schema is modified
* manually.
*
*
* Value could be any absolute URI, like {@code http://example.org/some.xsd}.
* It is also possible to specify the empty string, to indicate
* that the schema is externally available but the location is
* unspecified (and thus it's the responsibility of the reader of the generate
* schema to locate it.) Finally, the default value of this property
* {@code "##generate"} indicates that the schema generator is going
* to generate components for this namespace (as it did in JAXB 2.0.)
*
*
* Multiple {@link XmlSchema} annotations on multiple packages are allowed
* to govern the same {@link #namespace()}. In such case, all of them
* must have the same {@link #location()} values.
*
*
*
Note to implementor
*
* More precisely, the value must be either {@code ""}, {@code "##generate"}, or
*
* a valid lexical representation of {@code xs:anyURI} that begins
* with {@code :}.
*
*
* A schema generator is expected to generate a corresponding
* {@code
