[bpel-dev] The specification is unclear

[Joni Lee <webcokies@xxxxxxxxx>]

Would somebody please help me? The specification is unclear. Under 8.4.1 it says, selection results of copy operation cannot be multiple XML information items, while under 8.2.1 it says the xPath query can be: a collection of XML infoset items e.g. $myFooVar/lines/*

The * means the query selects multiple elements under $myFooVar/lines for the copy
------------------------------------------------------------------------------------------------
[8.4.1 Selection Result of Copy Operations]
"<copy> operation must be an EII, AII or TII. Selection failure must be thrown when the FROM-spec selects multiple XML information items..."
-------------------------------------------------------------------------------------------------
[8.2.1]
Evaluation of a WS-BPEL _expression_ or query will yield one of the following:
a collection of XML infoset items e.g. $myFooVar/lines/*
