Issues with fm-indexterm

Hi all,

I am working with Framemake11 and DITA 1.2. Fm-indexterm is defined the commonElements.eddmod.fm.  I added  fm-indexterm to the general rule list for all the elements I would use it in,  such as the following:

(<TEXT> | ph | codeph | filepath | msgph | userinput | systemoutput | b | u | i | sup | sub | uicontrol | xref | fm-xref | cmdname | msgnum | varname | tm | note | dl | ul | ol | sl | codeblock | msgblock | fig | image | table | fn | menucascade | draft-comment | keyword | term | indexterm | fm-indexterm)*

I can insert an fm- indexterm without error, but when I save, I consistently get the following xml error:

Error at file C:\Untitled2.dita.058, line 38, char 47, Message: Unknown element 'fm-indexterm'

This is happening in tasks, concepts, and references.

Any ideas on what I need to do to fix this?

Thanks in advance. This list is a life (and time) saver.
