Ah, thanks that is a good suggestion.

Eh, at least to my question, but I am beginning to realize that I have 
asked the wrong question. I wanted to modify the xmltok.el library that 
comes with nxml so that it could be used with mumamo in a better way 
than now. I want to jump over regions that are not parseable by 
nxml-mode. (I thought I had already done that, but forgot about xmltok.el.)

I will ask some questions about that in a separate thread.
