It's fine to have tools to convert in or out of canonical formats.
That's what the current xml2rfc does, convert out of it.

If there are a significant number of people who want to write in
stylized HTML, it might make sense to pay for a tool to turn that
into canonical xml.  If it's only one or two people, well, maybe not.
