Not as far as I remember. If you are going to include these manually, 
remember you'll need to change the URIs...

An easier solution if you need a non-modularized XTM version of this topic 
map is to use the Omnigator to load the HYTM version and then use its 
Export plug-in to export to XTM. You lose the comments and don't have 
control over the order of the elements, but that shouldn't be a problem for 
your purposes.

There are no standard extensions for topic maps. At Ontopia we generally 
use ".xtm" and ".htym", but I had my own reasons for using .xtmm (XTM 
module) and .xtmp (XTM template) for topic maps whose only purpose in life 
is to be merged into something else.
