Are you looking for things like XML Schema, Relax-NG, Schematron and so on? 
Or are you looking for graphical methods?

If the latter, I'm not aware of any formal methods, but a number of tools do 
represent schemas using graphical methods. However, in my experience, in 
most cases the graphical representations only capture a fraction of the 
information you need, and while sufficient for a screen based representation 
with which you can click to get more information, they probably don't 
translate well into paper based representations.

All,

Is there a popular notation for modeling a vocabulary? I'm accustom to
ERD's for database data modeling. I tend to use that for data modeling
XML vocabularies, but I want to know if there is a better way to do
this.
