2.6 Message Reference
Message Reference
The Message Reference Component[top]
The Message Reference Component
A message reference component refers to a named message that
forms part of an operation.
Message reference components are local to a given port type
operation component, they cannot be referred to by QName
The properties of the Message Reference Component are as follows:
-
{name} An NCName as defined by [XMLNS].
-
{variety} One of input, output or fault.
-
{message} A reference, by QName (see [QName resolution]), to a named message component.
For each message reference component in the {messages} property of a
port type operation component the {name} property must be unique.
XML Representation of Message Reference Component[top]
XML Representation of Message Reference Component
The XML representation for a message reference component is
an element information item with the following Infoset properties;
-
A [local name] of input, output or fault
-
A [namespace name] of
http://www.w3.org/2003/03/wsdl
-
One or more attribute information items amongst its [attributes] as
follows;
-
An optional name attribute information item
as described below in [ ].
-
A message attribute information item
as described below in [ ].
-
Zero or more namespace qualified attribute information items.
The [namespace name] of such
attribute information items MUST NOT be http://www.w3.org/2003/03/wsdl.
-
Zero or more element information items amongst its [children], in order,
as follows;
-
An optional documentation element information item (see [Documentation]).
-
Zero or more namespace qualified element information items. Such element information items MUST be
a member of one of the element substitution groups related
to input, output or fault children of port type operations described
in [Language Extensibility].
name attribute information item with input, output or fault [owner][top]
name attribute information item with input, output or fault [owner]
The name attribute information item identifies a given message reference
element information item within a given operation element information item.
The name attribute information item has the following
Infoset properties;
The type of the name attribute information item is xs:NCName.
message attribute information item with input, output or fault [owner][top]
message attribute information item with input, output or fault [owner]
The message attribute information item refers, by QName, to a message component.
The message attribute information item has the following
Infoset properties;
The type of the message attribute information item is xs:QName.
Mapping Message Reference's XML Representation to Component Properties[top]
Mapping Message Reference's XML Representation to Component Properties
The mapping between the properties of the Message Reference Component (see
[The Message Reference Component]) and the XML Representation of
the message reference element information item (see [XML Representation of Message Reference Component]) is
as described in [tab_MessageReference_Mapping].
