Using GrXML Grammars
Capacity Private Cloud provides complete support for SRGS grammars in the XML-based format called GrXML. The grammar-writing tutorial in this guide presents examples in both ABNF and GrXML; the two formats are equivalent, and there is no real advantage to using one over the other.
If you have existing GrXML grammars, you can load them as normal.
If you are new to writing GrXML grammars, the SRGS specification includes examples and a complete guide to the syntax of both GrXML and ABNF.
