How can I apply a character format to all fm-xref elements in my book?

[katk70962034]

I want to apply a character format (italic, blue) to all fm-xref elements in a composite fm doc generated from dita files. I can't apply text formatting in the EDD to the fm-xref element. (I can apply it to the xref element, but this doesn't affect my fm doc.)

How do I solve this?

Thanks!
