There are many schema fragments that together 
comprise the entire Invoice model (or any one of the many documents).

I am unfamiliar with SAP PI to guide you, but I 
have some general comments that I hope will help.

Typically a user community works with a subset of 
UBL and not the complete entire document 
structure.  There are many aspects of the common 
structure that are not used by the invoice, and 
the invoice itself is general purpose and could 
be subset to be only that that your user community plans to use.

Is it your intention to support the entire UBL 
Invoice, or are you targeting your work to a user 
community that has defined a subset of UBL?

Have you considered transforming an instance of 
UBL into an instance of XML already supported by 
SAP?  Using a technology such as XSLT you can 
convert documents to and from a SAP format and 
the subset of UBL that your user community plans 
to use.  Then your maintenance is limited to the 
transformations and you don't have to "touch" the 
SAP code that already recognizes its own existing XML vocabulary.

This transformation approach would also allow you 
to implement the two different two-pass 
validation approaches found in the UBL 
specification and in the UBL Customization document.

I hope this helps, though I understand I did not answer your question directly.
