Bummer.  Well, as a compromise, are the explanation messages (in HTML)
separate from the helpwanted links?  It would at least help if the
current <m:explanation> could be served up via SOAP as:

<m:explanationfeedback>
  <![CDATA[
   <p class="helpwanted">
     <a

href="http://validator.w3.org/feedback.html?uri=;errmsg_id=64#errormsg"
   title="Suggest improvements on this error message through our
feedback channels"
     >&#x2709;</a>
   </p>
]]>
</m:explanationfeedback>

and

<m:explanationtext>
  <![CDATA[
   <div class="ve mid-64">
   <p>
     The element named above was found in a context where it is not
     allowed. This could mean that you have incorrectly nested elements
     -- such as a "style" element in the "body" section instead of
     inside "head" -- or two elements that overlap (which is not
     allowed).
   </p>
   <p>
     One common cause for this error is the use of XHTML syntax in HTML
     documents. Due to HTML's rules of implicitly closed elements, this
     error can create cascading effects. For instance, using XHTML's
     "self-closing" tags for "meta" and "link" in the "head" section of
     a HTML document may cause the parser to infer the end of the "head"
     section and the beginning of the "body" section (where "link" and
     "meta" are not allowed; hence the reported error).
   </p>
   </div>
]]>
</m:explanationtext>

Is this possible (simply)?


Now, with regards to massaging the current explanation files, I hadn't
noticed that some of the message paragraphs, are filled with <a>, <code> 
and other tags.  So, I'm not sure how you'd convert the messages to a
text-only format unless you kept a separate version of the error for the
SOAP and standard validator.  You certainly couldn't keep a text-only
version and reconstitute the HTML from it.

I'm guessing  a better solution might be to keep the existing messages
in the current format and, instead, code a processor for SOAP users that
parses them into plain text (or at least more distinct blocks of HTML)
much like app developers now must do.  That way, the fancy parsing rules
are coupled to the messages themselves in the same app -- yours.  Sure,
changes to the message format would require adjusting the SOAP
processing code on the validator -- but it wouldn't require every SOAP
consumer to re-work their apps.  And you would have knowledge of when/if
those changes were going to happen.

Yeah it's odd.  To be accurate, what is left is '&#x2709;' which is the
content of the <a> tag.  So, what I said is correct.
