You are using internal comands of the NFSS in Your itma.sty. Those comands
are privat and they may change. So when the next release of the NFSS will
be published Your new style may have to be rewritten. The best way is to
write a new environment which uses only the exported commands or its own
privat font selection. In Modula2 (or Oberon) You will find the same thing
as `opaque' data types. It's a `save' way because You can change the NFSS
as You like until You never change the global seen comands.
