Issue - 29 - Simplification of XPath expressions

Submitter: Assaf Arkin
Date submitted: 25 June 2003
Categories: enhancement
Document: Specification
Description:

Consider the following expression:

getVariable( getVariable( 'name' ) ) An expression of this form is supported by the current specification, but hinders the ability to perform static analysis on the use of variables within the activity. This could be mitigated by clarifying the use of BPEL functions such that their input arguments must be literals. However, this goes against the XPath specification that makes no such restriction. An alternative would be to use XPath variables which are precluded from this dynamic behavior as per the XPath specification. (Assuming this restriction is still part of XPath 2.0 and XQuery).
