MXG (Metasearch XML Gateway) does not allow arbitrary XHTML either.
That's exactly the thing the metasearchers are trying to get away from.
They expect well-formed SRU responses so they can find the records in
the response easily and do something useful to them. Returning HTML, or
even XHMTL, still leaves them screen scraping and holding their breaths
hoping you don't change the format of your output.

For the metasearchers, the input part is the easy part. They figure
your query grammar doesn't change nearly as often as your output.

But it sounds like you expect the customers for this service to be
humans at browsers, not applications. The standards bring little value
to that arena. The humans are flexible enough to find the box to stick
their one or two words into.
You can use CQL as the query grammar embedded inside your own unique
URL's and return arbitrary XHMTL. But CQL wasn't designed to be a human
entered query grammar. It does simple stuff well, but tricky stuff gets
All-in-all, this sounds much more like OpenSearch than SRU or even MXG.
