If XMLREF is true, then REFELEMENTQUALIFIED is true if the XML namespace that contains the global element has elementFormDefault as "qualified" in its schema. If not specified, this parameter defaults to the value of ELEMENTQUALIFIED for the class.

This parameter is ignored for direct use of XMLExport -- it is only available for use by %XML.Writer or SOAP support.

If XMLREF is true, then REFNAMESPACE is the XML namespace that contains the global element or attribute. However, if the default XML namespace is to be used (the XML namespace of the containing class for primitive types and the actual XML namespaces for complex types), then this parameter may be omitted.
This parameter is ignored for direct use of XMLExport -- it is only available for use by %XML.Writer or SOAP support.

A comma-separated list of class names for XMLPROJECTION = CHOICE, ELEMENT-CHOICE or WRAPPED-CHOICE.

Specified as true (1) if this property comes from an XML schema reference to a globally defined element.
This parameter is deprecated and has been replaced by XMLREF.

Controls whether input and/or output XML projections are done for this property. Default is "INOUT". Other possible values are "IN", "OUT", "CALC" Calculated properties default to CALC which is like OUT except input is ignored instead of generating an error.

The XML name for a collection item.

The XML name for the array key of a collection item.

This is the XML element or attribute name to be used for this property.

The XMLNIL property parameter controls the use for a property of the xsi:nil attribute by XMLExport and the nillable attribute by XMLSchema.

If XMLNIL=1, then properties of the class with value = "" (null) are XMLExported in the format <propname xsi:nil="true"/>.

The exception is that string properties with value = "" are always exported as <propname/> if the class parameter XMLIGNORENULL=1 even if XMLNIL=1.

The XMLNIL property parameter overrides the XMLNIL class parameter for the property where it is specified.

XMLPATTERN is a placeholder used to document the pattern facet of XML Schema types. No runtime behavior is currently implemented to support the pattern facet semantics. The XMLPATTERN is only used to include the pattern facet in schemas geenrated based on the class.

The type of XML projection for this property.

• NONE indicates that the property is not to be projected to XML. The XMLPROJECTION for private properties defaults to NONE. Private properties are not automatically projected but can be forced to project by specifying a value for this parameter.
• ATTRIBUTE indicates that this property is projected as an attribute.
• XMLATTRIBUTE indicates that this property is projected as an attribute from the default XML namespace using the xml: prefix.
• CONTENT indicates that this property is the only element for this class and its value is projected with no enclosing tag as the class' value.
• ELEMENT indicates that this property is projected as an XML element or, in the case of a collection, a list of element with no wrapping tag.
• WRAPPED indicates that this property is projected as an XML element with an addtional wrapping tag or, in the case of a collection, a list of elements wrapped in a tag for the collection.

The XML projection will default to WRAPPED for a list or array collection property and ELEMENT for other public properties.

COLLECTION is now deprecated and replaced by its synonym WRAPPED. ELEMENTREF value is now deprecated and replaced by the use of the XMLREF parameter.

Specified as true (1) if this property comes from an XML schema reference to a globally defined element or attribute.
This parameter is ignored for direct use of XMLExport -- it is only available for use by %XML.Writer or SOAP support.

How to project references to XML.

• SUMMARY indicates that only the summary properies of the referenced class are used to represent the reference. SUMMARY is the default. Note that by default all properties are of the referenced class are in the summary.
COMPLETE indicates that all properties of the referenced class are used to represent the reference.
ID indicates that the id of a persistent or serial class is used to represent the reference.
OID indicates that the oid of a persistent or serial class is used to represent the reference. The form of the oid will be classname,id.
GUID indicates that the GUID of a persistent class is used to represent the reference.

Controls the line ending behavior for a character stream property.

• If XMLSTREAMMODE="block" (the default), the normalized XML data is copied unchanged to the stream.
If XMLSTREAMMODE="line", the XML data is broken into lines separated by the streams LineTerminator sequence.

How to interpret the type of this property.

• EXPLICIT indicates that only this property's explicitly specified type in XML will be projected to XML.
CHOICE indicates that the schema for this property uses the XML schema choice group to allow multiple XML types for this property. The Cache classes for these types are specified by the XMLCHOICELIST parameter or are all subclasses of this property's type if no XMLCHOICELIST parameter.
SUBSTITUTIONGROUP indicates that the schema for this property uses the XML schema substituionGroup to allow multiple XML types for this property. The Cache classes for these types are all subclasses of this property's type.
