I came accross this in reading the sourcecode, but noticed it wasn't reported here yet.
Sourcode cite:
" # MISSING : <nowiki> filtering"
It's not only nowiki filtering but pretty much any kind of 'dont touch this' method. I think it's probably best trying to somehow hook into the the real parser instead of copying part of the parser that filters out parts not to touch.
