Re: [ebxml-bp] Episodical memory requirement

Anders,

OK.  That's another thing ; -)

I've been working on that aspect thru the ebContext mechanism.

This does indeed allow you to reference content in documents
based on XPath references.

Now - you still need to tie that back into conditionals on
the BTA - and I've are targetting the beginsWhen / endsWhen
mechanism for that.

In the model example there's one of these too.  So you
create a boolean true/false in the begins/endsWhen - and then
that condition name is also in the ebContext declarations.

Something like :  validOrderType = 'true'

If you download the document on ebContext - it explains this:-

Hope this provides the other piece of what you are wanting.

DW.
