Hi Matt,

have you had a look at http://geuz.org/gmsh/doc/texinfo/gmsh-full.html#SEC42 and 
http://geuz.org/gmsh/doc/texinfo/gmsh-full.html#SEC64 ?

...
In the MSH file format (see section 9. File formats), if physical entities are defined, the output mesh only contains 
those elements that belong to physical entities.
...

Cheers,

Dave
