Dear all,

I have some common macro and element definitions which I would like to  
import into different ODD files (with different schemaSpecs).

Right now I have tried these possibilities:
1. copy & paste ;-)
2a. xincluding every macroSpec separately
2b. xincluding a specGrp with the macroSpecs
3. modulerefing a relaxNG file with the appropriate definitions

Are there any more/better and what is the preferred way?

Many thanks
