[oXygen-user] Custom action to process a document and update an element?

For the DITA RelaxNG support that will be in DITA 1.3 I want to implement an action that can be applied to RNG document type shell grammars that looks at each referenced module, gets its domains attribute contribution (which will be in a specific subelement within the referenced module, and add it to the right place in the shell (a pattern named “domains-att”). This is of course easy to do with XSLT. My question: what’s the best way to set this up in Oxygen so that I can just do an “update domains attribute” action when editing a document type shell schema?
