Subject: Issue - 106 - ASSERT activity.

This issue has been added to the wsbpel issue list. 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 document with the title in the "Issues" folder of the WSBPEL TC document list - the next posting 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.

Issue - 106 - ASSERT activity.

Status: open
Date added: 18 Mar 2004
Submitter: Maciej Szefler
Date submitted: 18 March 2004
Description: I'd like to propose the addition of an assertion facility to the BPEL language. Specifically I'd like to see <precondition> and <postcondition> elements added to the list of standard elements, something along the lines of:
	    <expression language="XPath">
	    <expression language="XPath">



Interpetation of the <pre-/post-condition> elements would be optional, but if assertions are enabled the expressions must evaluate to "true" or else the process instance is immediately terminated (ala <terminate>). Assertions would be available to both executable and abstract processes. -standard argument for assertions goes here-.
