This document defines an element identifier syntax for WSDL 1.1 elements.

This section defines a fragment identifier syntax for identifying elements of a WSDL 1.1 document. This fragment identifier syntax is compliant with the []. This document is primarily based upon []. There is a substantial difference between the WSDL 1.1 and WSDL 2.0 fragment identifiers.WSDL 2.0 defines fragment identifiers with respect to the WSDL 2.0 component model, whereas WSDL 1.1 defines XML element and attribute syntax only. Because there is no WSDL 1.1 component model, the WSDL 1.1 fragment identifiers identify WSDL 1.1 elements. Note: the fragment identifers identify the WSDL 1.1 elements prior to any processing of the WSDL document, such as validation, inclusion, imports, schema type validation, etc. Note further: WSDL 1.1 fragment identifiers require a targetNamespace so WSDL 1.1 documents without a targetNamespace will not have fragment identifiers.

A WSDL 1.1 fragment identifier is an XPointer [], augmented with WSDL 1.1 pointer parts as defined below. Note that many of these parts require the pre-appearance of one or more xmlns pointer parts (see 3.4 Namespace Binding Context in []). The pointer parts have a scheme name that corresponds to one of the standard WSDL 1.1 element names, and scheme data that is a path composed of names that identify the elements. The scheme names all begin with the prefix "wsdl11." to avoid name conflicts with other schemes. The names in the path are of type either QName, NCName, IRI, URI, or Pointer Part depending on the context. The scheme data for WSDL 1.1 extension elements is defined by the corresponding extension specification.

For QNames, any prefix MUST be defined by a preceding xmlns pointer part. If a QName does not have a prefix then its namespace name is the target namespace of the WSDL 1.1 document.

The fragment identifier is typically constructed from the name property of the element and the name properties of its ancestors as a path according to . The first column of this table gives the name of the WSDL 1.1 element. Columns labeled 1 through 3 specify the identifiers that uniquely identify the element within its context. Identifiers are typically formed from the name property, although in several cases references to other elements are used. These identifiers are then used to construct the pointer part in the last column. The fragment identifier in a WSDL 1.1 element IRI-reference MUST resolve to some element as defined by the construction rules in .

This section provides a syntax for IRI-references for all elements found in a [] document. The IRI-references are easy to understand and compare, while imposing no burden on the WSDL 1.1 author.
