Built-in schemas

Gosu includes several XSDs in the gw.xsd.* package. The following table lists the built-in XSDs.

Description of the XSD	Fully qualified XSD package name
The SOAP XSD	`gw.xsd.w3c.soap`
SOAP envelope XSD	`gw.xsd.w3c.soap_envelope`
WSDL XSD	gw.xsd.w3c.wsdl
XLink XSD for linking constructs	`gw.xsd.w3c.xlink`
The XML XSD that defines the attributes beginning with the `xml:` prefix, such as `xml:lang`	gw.xsd.w3c.xml
The XML Schema XSD, which is the XSD that defines the format of an XSD	`gw.xsd.w3c.xmlschema.Schema`

The metaschema XSD that defines an XSD

The definition of an XSD is itself an XML file. The XML Schema XSD is the XSD that defines the XSD format. The XML Schema XSD is also known as the metaschema. This schema is in the Gosu package gw.xsd.w3c.xmlschema. You can use the metaschema for building or parsing schemas.

Example

The following code parses the metaschema.

var schema = new gw.xsd.w3c.xmlschema.Schema()
schema.Element[0].Name = "Element1"
schema.Element[0].ComplexType.Sequence.Element[0].Name = "Child"
schema.Element[0].ComplexType.Sequence.Element[0].Type = new javax.xml.namespace.QName( "Type1" )
schema.ComplexType[0].Name = "Type1"
schema.print()

This code prints the following:

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:element name="Element1">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="Child" type="Type1"/>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
  <xsd:complexType name="Type1"/>
</xsd:schema>

Gosu does not provide a way to inject a schema into the type system at run time.
