OK, this is very useful.  I would propose two things:

1. commit the not-equal filter to mkgmap
2. implement include files, possibly also a mkgmap --include option
so that you could include the "Chinese sub-style" from the command line
when needed, for any style whose definitions do not conflict with those
in the sub-style.

Your example shows that the name rules could be best defined in a
style file.

Can you submit a patch for implementing include files in the style parser?
And can you please resubmit the not-equal filter?
