I'm not sure though. I found other materials on Biztalk indicating that theortically it is an LL(k) parser which can be set to "unbounded" lookahead, and that is not consistent with implied limitations that  you found below.

So who knows really?

Interesting. The problem the author observes at the end is one we discussed
at the F2F. It can be solved in DFDL using regular expressions, or by
multiple parsing. It looks like BizTalk does not support this? If so it
means there are a large class of data structures that it can not easily
represent.

I found this link to the Microsoft biztalk style of annotations. Thought
some of you might like to surf it. There's no news here. Just indicates a
style.
