Every ctor of Filters registers a MimeType that they can handle.  So, 
there shouldn't be any two-filters that registers same MimeType.

What you can possibly do is:
1) Create some abstract class called FilterMarkup or something like that 
and have all those *common* functions as overrides in FilterMarkup.
2) Derive FilterHtml and FilterCHM from FilterMarkup.

Hopefully, this will solve the above collision.

How are you parsing CHM file, using, chmlib?

You need to add a tile-template for CHM files.  Look into 
Tiles/template-docs.html and Tiles/TileDocs.cs.
