Use the source ! Sorry, this is kind of a lame answer but it's the best
I can really provide without spending a lot of time. See
xmlDefaultExternalEntityLoader()
in xmlIO.c and how it uses xmlNewInputFromFile()

There is no mechanism for callback in the serializer, I don't see how
this could easilly be added. I also don't fully underdstand how this
relates to XSLT and transformation time. But for the serializer this
is synchronous. Also you can't just plug XML in the document as text and
expect that to work as you seems to think because all the <, > and &
in said text will be properly escaped to < > and & as expected
from a serializer. In a nutshell you can't mix semantic layers like this.
