execmem_exec_t, unconfined.te and nsplugin

[Joe Nall]

libsepol.print_missing_requirements: nsplugin's global requirements  
were not met: type/attribute execmem_exec_t
/usr/bin/semodule_link:  Error while linking packages
make[1]: *** [validate] Error 1

error: Bad exit status from /var/tmp/rpm-tmp.XoIIV1 (%install)

I'm trying to build an mls policy with nsplugin defined as a module in  
modules-mls.conf. nsplugin depends on execmem_exec_t which is defined  
in unconfined.te which is _not_ a module in modules-mls.conf, creating  
the error above.

Is there a better place to declare execmem_exec_t (userdomain.te?).
