Guidelines for Using XML Namespaces and Prefixes with Web Service Descriptors
Use the following guidelines for assigning XML namespaces and prefixes to variables that will be used with web service descriptors:
If an IS service signature contains a variable name in the format
prefix:
localName, you must specify a URI as the value of the
XML namespace property for that variable.
If an IS service is exposed as an RPC/Literal or RPC/Encoded web service operation, then the top-level field name in the service signature should not be in the format
prefix:
localName and should not be associated with an XML namespace.
If an IS service is exposed as a Document/Literal web service operation, then any field name in the service signature can be in the format
prefix:
localName, but it must also be associated with an XML namespace.
