Subject: Issue - 165 - clarification of the default NS URI for expression and query language
This issue has been added to the wsbpel issue list with a status of "received". The status will be changed to "open" if the TC accepts it as identifying a bug in the spec or decides it should be accepted specially. Otherwise it will be closed without further consideration (but will be marked as "Revisitable")
The issues list is posted as a Technical Committee document to the OASIS WSBPEL TC pages on a regular basis. The current edition, as a TC document, is the most recent version of the document entitled in the "Issues" folder of the WSBPEL TC document list - the next posting as a TC document will include this issue. The list editor's working copy, which will normally include an issue when it is announced, is available at this constant URL.
Currently, http://www.w3.org/TR/1999/REC-xpath-19991116 is used as the default value of both expression language and query language, which represents XPath 1.0.
In order for us to make use of XPath 1.0 within BPEL, the BPEL spec needs to define additional semantics for the cross-language bindings. Those details are actually specific to BPEL language in a sense. Strictly speaking, it is not appropriate to "hijack" the W3C namespace for our own use.
(This was raised by Chris Keller in the course of issue 89 : Handling Unrecognized Query/Expression Languages discussion at the face-to-face today)
Submitter's proposal:
Replace the following text in BPEL spec:
The default value for this attribute is XPath 1.0, represented by the URI of the XPath 1.0 specification: http://www.w3.org/TR/1999/REC-xpath-19991116.with:
The default value for this attribute is: "urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0", which represents the usage of XPath 1.0 within WS-BPEL 2.0. The URI of the corresponding XPath 1.0 specification is: http://www.w3.org/TR/1999/REC-xpath-19991116.
