The critical first step is generating "well-formed XML".  I.e.
basic lexical/syntactic correctness, ignoring semantic constraints 
("validation").
Most critical is no elements without closing tags.  For example <hr>
must be either <hr></hr> (valid XML, not valid HTML) or <hr/> (valid either).

Emiotting <hr/> has the advantage that it is correct for both XML and (modern) 
HTML.

Once this is taken care of, we're a big step there.

Emacs nxml mode should be sufficient to check well-formedness.
