help with adding external grammar reference,from whithin a xml gra

[cornelyus]

Hello

So i have some grammars i am using, but there are rules common to these
different ones. I thought i could create an external grammar with these
rules, and i could reference it from the original one.

Can't find real examples, or good documentation on this.. only
http://www.w3.org/TR/speech-grammar/#S2.2.2 and it lacks info.. anyone care
to help?

My grammars are all in .xml format and in the same folder.

thank you,

Ricardo
