Processing such very big files in XSLT is will not lead to good
performance. There's a certain limit of what can be done efficiently,
depending on the amount of RAM available. Mike Kay pointed out that
processing XML files of size 10MB "is about the limit, depending of
course on how much memory you have" .

I'll need some time to look into this, but it may be useful if in the
meantime you think of splitting your huge XML file into smaller files
and how to organise their processing.
