Xmlgen.getxml Nested Cursors with LONG RAW and BLOB Data Types

Question

I am trying to use a nested cursor with xmlgen.getxml that has a long raw or blob column. In either case, it will not return to me any data in the xml document pertaining to that LONG RAW or BLOB column. If I do not use a nested cursor, it works fine.
Example:
SELECT xmlgen.getxml('SELECT x, CURSOR(SELECT y FROM y_tab WHERE y_tab.x_id = x_tab.x_id) y FROM x_tab') FROM dual;
This will not produce the information I am after.
However, simply running:
SELECT xmlgen.getxml('SELECT y FROM y_tab WHERE y_tab.x_id = <somevalue>') FROM dual;
Works???
Any ideas out there? Does anyone know if DBMS_XMLQUERY has this limitation?
Thanks,
Brad

It doesn't appear that I am able to attach the PDF files.  Can you supply your email (or I can supply mine) so I can send you the three files:
1.)  A good PDF (manually extracted from our old application)
2.)  Dump of the same PDF file (includes header/footer info)
3.)  A partially fixed PDF file (but some of the pictures / pages are cut off - specifically pages 3,5,9,10,12,14)
The way that we have tried to fix the file (in example 3 above) is the following:
a.)  Find the First Occurrence of "%PDF-"
b.)  Find the Last Occurrence of "%%EOF"
c.)  if the first "%PDF-" is found AND the last "%%EOF" is found, then
   i.)  Remove all data before the first %PDF-
   ii.)  Remove all data after the last %%EOF
Let me know if you need any other information.
Thanks,
Mike
