Subject: Issue - 13 - Future Usage of XPATH 2.0 and XQuery 1.0


This issue has been added to the wsbpel issue list. It is in the current version of the list at wsbpel document 2656, It is hoped to have a fixed url for the ever-changing list.

Issue - 13 - Future Usage of XPATH 2.0 and XQuery 1.0

Origin: Initial issue log, item 6 (document details)
Date submitted: 23 May 2003
Submitter: Original authors group
Description:
The current specification mandates support for XPATH 1.0 and leaves the door open for other query and expression languages fir the future. XPATH 2.0 and XQuery 1.0 are the obvious future candidates. There are two related issues here.

A. Should we adjust the BPEL syntax (element rather than attribute content for XQuery) to prepare for the use of XQuery in future?

B. Should we change the mandatory dependency for query and expression support from XPATH 1.0 to XPATH 2.0? Keeping in mind that XPATH 1.0 is very widely deployed whereas XPATH 2.0 is not yet a recommendation, although it is likely to become one in roughly the same timeframe as the final release of the specification produced by the WSBPEL TC.
