Customizing XML serialization

The following attributes are used to change the default serialization of BDL into XML, and vice versa. Some attributes cannot have values, some may have values, and some attributes have mandatory values.

The following attributes cannot have values:

Table 1. XML Serialization customizing - Attributes that cannot have values
Attribute	Definition
XMLOptional	Define whether the variable can be missing.
XMLNillable	Define an XML element to be explicitly null and serialized with the `xsi:nil="true"` value.
XMLElement	Map a BDL simple data type to an XML Element.
XMLElementNillable	Define the default for all element members in a `RECORD` (defined by `TYPE` or `DEFINE`) to be serialized as `xsi:nil="true"` if NULL.
XMLAttribute	Map a BDL simple data type to an XML Attribute.
XMLBase	Set the base type of an XML Schema simpleContent.
XMLAll	Map a BDL Record to an XML Schema all structure.
XMLChoice	Map a BDL Record to an XML Schema choice structure.
XMLSequence	Map a BDL Record to an XML Schema sequence structure.
XMLSimpleContent	Map a BDL Record to an XML Schema simpleContent structure.
XSComplexType	Map a BDL Record type definition to an XML Schema complexType.
XMLList	Map a one-dimensional array to an XML Schema list.
XMLSelector	Define which member of an XMLChoice record is selected.
XMLAny	Map a `xml.DomDocument` object to a wildcard XML element node.
XMLAnyAttribute	Map a BDL one-dimensional dynamic array of a record with 3 strings to XML wildcard attributes.

Values are mandatory for the following attributes: (for example, XMLName="myname")

Table 2. XML Serialization customizing - Attributes that must have values
Attribute	Definition
XMLName	Define the XML Name of a variable in an XML document.
XMLNamespace	Define the XML Namespace of a variable in an XML document.
XMLType	Force the XML type name of a variable.
XMLTypenamespace	Force the XML type namespace of a variable.
XSTypename	Define the XML Type Name of a BDL type definition.
XSTypenamespace	Define the XML Type Namespace of a BDL type definition.
XMLElementNamespace	Define the default XML namespace of all children defined as XMLElement in a Record.
XMLAttributeNamespace	Define the default XML namespace of all children defined as XMLAttribute in a Record.

Values may be required for the following attributes: (for example, XMLOptimizedContent="image/*")

Table 3. XML Serialization customizing - Attributes that may have values

XMLOptimizedContent	Set on STRING or BYTE data type so that such string content represents a file on disk to be transmitted as base64 binary in SOAP via HTTP attachment.
