TARGET: HT, Section 6.2 Xpath Extension Functions

DESCRIPTION: It's not clear whether the functions require string literals
for the part, task, or LPG name params or whether callers can use
expressions for these values. In the ws-bpel 2.0 spec there are similar
instances where functions that accept the name of a resource (i.e.
bpel:getVariableProperty ) require that the name of the resource is passed
as a string literal. This is beneficial for static analysis and as well as
makes the behavior of the process/task easier to follow.

PROPOSAL: Add some text to the description of the Xpath extensions to
indicate that the part, task, and LPG params must be passed as string
literals. A similar change is required to the B4P spec. Formal proposal to
follow if the issue is opened.
