Unknown or X-extended tags

Both Mosaic and Lynx currently ignore any tags they don't understand. 
( probably the only reasonable things right now, considering the 
  relatively undefined state of HTML ) 
They also both seem to ignore any parameters they don't understand. 
( like "<CODE LANG=C>" for example. ) 
 
Is this behaviour likely to continue, and be considered the "RIGHT 
THING" to do ? 

I would like to include other custom non-HTML markup in my HTML
documents. I could use comments, <!-- My-Markup-Tag -->, but will
that prevent my easily using other SGML tools on that text? 

I would think that it would be desirable to be able to consider
HTML documents as a subset of other SGML markedup text - which 
would imply that proper programs ought to accept non-standard 
tags. But, if we want to reserve space for *standard* HTML 
extensions, then I can see that a standard might want to leave
undefined tags "undefined" - i.e. not guarantee any semantics
including non-interpretation. 

Should the <X-*> namespace be reserver, as in mime and rfc822 ? 
( That doesn't seem to be a better solution to me. )
