>Hello all,

>Here is a proposal to vote for issue 90 (
>http://www.choreology.com/external/WS_BPEL_issues_list.html#Issue90):
>
>-----------------
>Proposed solution:
>
>Introduce a new form of the <from> element:
>
><from location=”document-location” query=”queryString”?/>
>
>The query attribute has the same semantics as the normal query 
>attribute on the <from> element, i.e. it must be an absolute 
>location path and select exactly one node. If no query is 
>specified, the root node of the XML document is selected. The 
>document-location is a URL (as defined in RFC
>2396) that refers to an XML document, and in the case that the 
>XML document is not valid and/or a single node cannot be 
>returned, a selectionFailure fault should be thrown by a 
>compliant implementation. The document that is retrieved from 
>the URL is considered static in the same way the business 
>process definition is considered static during execution. 
>Furthermore, the external document is considered part of the 
>business processes that reference it, and conversely, the 
>business process definition should not be considered complete 
>or valid without the external document. A change in the 
>external document should be treated in the same way as a 
>change in the business process definition.
>
>This <from> form can be used in conjunction with all the <to> forms.
