Subject: Re: [ubl-ndrsc] FW: More ASBIE Confusion (in UBL)

it may be my misunderstanding the question but  if the core of this is "what
types do we give for ASBIEs?" then the answer should be none.  ASBIEs in
our schemas are expressed in the documentation only - they describe the semantics
of the ASBIE.  so, as Mike says, we are defining ABIEs contained within other
ABIEs.  the point is that when an ABIE is contained within another ABIE it
has a meaning specific to that containment.  An Invoice Line when it appears
within an Invoice is not a good example, a better example is that  a Line
Item contained in an Invoice Line  means something different to a Line Item
contained in an Order Line.  We express that meaning as an ASBIE. By definition,
an ASBIE merely records the use(via containment in our document models) of
another ABIE (for a particular context).  This can be seen when we have more
than one ASBIE between the same two BIEs. Every time the ASBIE is used it
has a unique meaning.  


So, ASBIEs do not need the same tangible expression as ABIEs or BBIEs and
therefore it is not useful to try and make them reusable types.  To go down
this path would just create additional complexity (as seen by the question
about naming) with no added value.
