Actually there are warnings in the documentation about being careful
using IOBuf interface. And it does seem like the output is a bit
corrupted every so often. I still need to check and see if it's
consistent or not.
Apply the stylesheet to the document and generate the output according
to output SAX and IObuf. It's an error to specify both SAX and IObuf.
NOTE: This may lead to a non-wellformed output XML wise ! NOTE: This may
also result in multiple files being generated NOTE: using IObuf, the
result encoding used will be the one used for creating the output
buffer, use the following macro to read it from the stylesheet
XSLT_GET_IMPORT_PTR(encoding, style, encoding) NOTE: using SAX, any
encoding specified in the stylesheet will be lost since the interface
uses only UTF8

I see, because I thought that we could win by not building the result
tree, but somehow optimizing it for output and then just outputting the
result using the callback interfaces or writing it out to a file.
