RE: [wsbpel] assign query without part?

["Muruga Chinnananchi" <muruga@collaxa.com>]

I am particularly concerned about these sentences in section 14.3.

"For XPath 1.0, the value of the query attribute MUST be an absolute
locationPath (with '/' meaning the root of the document fragment
representing the entire part). It is used to identify the root of a
subtree within the document fragment representing the part".

After reading this I am thinking that you can't have query without part.

But there is no "part" for element variables. So for element variables, we
should allow query attribute without part attribute. In this is true, I
suggest that we should change the content to:

"For XPath 1.0, the value of the query attribute MUST be an absolute
locationPath (with '/' meaning the root of the document fragment). It is
used to identify the root of a subtree within the document fragment".

Confusion about assign.
Spec section 14.3 says the following (see below).

"In the first from-spec and to-spec variants of assignment, an optional
query attribute may be used in executable processes, yielding the forms

 <from variable="ncname" part="ncname"? query="queryString"?/>
<to variable="ncname" part="ncname"? query="queryString"?/>

For XPath 1.0, the value of the query attribute MUST be an absolute
locationPath (with '/' meaning the root of the document fragment
representing the entire part). It is used to identify the root of a
subtree within the document fragment representing the part".

The question is:

For <to>, is it allowed to have "query" without "part"?. If it is not
allowed to have "query" without "part" then I would suggest to remove the
"?" for part, like below.
<from variable="ncname" part="ncname" query="queryString"?/>
<to variable="ncname" part="ncname" query="queryString"?/>

I have an element variable which doesn't have "part" and I want to use that
element variable in <to>. How do i  use element variables in <to>?
