I've prepared some DITA concepts outside FM. In these concepts, the name of the product is hauled in as a reference; the <ph> in the source files carefully reproduces the (naughty word ahead) formatting required by the product manager, namely <ph>productName <i>model</i></ph>.
How do I tweak my EDD so that <i> is seen as permissible content for <ph>? At the moment, my <ph> definition has got as far as
Element (Container): ph General rule: <TEXT> Text format rules In all contexts. Text range.
Or is there some other mechanism I could be using?
Thanks in advance for hints and tips.
