Details:

There are two problems with parsing embedded subdocuments
marked with DSC headers BeginDocument/EndDocument

- only the first EndDocument is looked for. This fails
  if the embedded document again contains embedded documents.

- the check for %%EndDocument is broken. There is only
a IS_END("Document") in the source, which only checks
that there is Document, but not that there is %%End before
that, which fails if an embedded document contains other
headers looking like this (like '%AI3_DocumentPreview: Header').

The attached patch should fix both.
