[oXygen-user] Find and replace with lowercase

If you're processing a doc with a DOCTYPE, the following thread includes
a python script that cloaks entities and restores the DOCTYPE:

In this case, however, it might just be easier to use sed on the xml
file to lowercase the file names to begin with.
