XOM API for Processing XML with Java

["Eric Wang" <jemroc AT gmail.com>]

Thank you for clearing this up for me Elliotte. I admit I was a bit
confused by that line in the documentation.

I was researching other solutions and stumbled upon Nux which builds
streaming serialization on top of XOM:
http://dsd.lbl.gov/nux/api/nux/xom/io/StreamingSerializer.html

Hopefully that helps someone out who has the same problem I do. It
would be nice to see this built-in into XOM though, to avoid
introducing another dependency. XOM already reads large and small
documents and writes small documents. The only thing missing from that
matrix is the capability to write large documents. Is this something
you would consider adding to XOM? Sorry if this proposal has already
been suggested before and rejected.

Thanks again,
Eric
