[rfc-i] xml2rfc: <vspace> only in .txt, not .html?

["Martin J. Dürst"]

I have a couple of drafts where I'm using <vspace> to make sure examples 
(URIs/IRIs) fit on a single line where possible. But that results in way 
too much half-empty lines in HTML (of course depending on the width of 
the browser). Is there a way to say that some <vspace>s should only be 
applied in .txt versions, and not in .html?

(This shows that certain problems in the traditional format go away or 
change in nature when we move to something more flexible.)

Regards,   Martin.
