Headers to Get Doctype, Warnings

Any chance doctype and warning count could be added to the headers of the html (and soap) outputs?

I'd love to see a:

    HEAD 'http://validator.localhost/check?uri=http%3A%2F%2Fwww.w3.org'
   
    200 OK
    [...]
    Content-Language: en
    Content-Type: text/html; charset=utf-8
    X-W3C-Validator-Errors: 0
    X-W3C-Validator-Warnings: 0
    X-W3C-Validator-Recursion: 1
    X-W3C-Validator-Status: Valid
    X-W3C-Validator-Doctype: XHTML 1.0 Strict

That way I could pull an HTML report and, from the headers, determine:
    "Your document failed validation with 3 errors and 1 warning - unknown doctype" or
    "Your document passed validation as xhtml 1.0 strict"
