wadl contains inline parameter documentation

[Jelmer Vernooij]

Launchpad's wadl inconsistently uses the standard wadl mechanism for documenting parameters and inline HTML tables.

It would be great if it could consistently use the WADL mechanism:

https://www.w3.org/submissions/wadl/#x3-250002.12

E.g.:

              <wadl:param style="query" name="file_type" required="false">
                <wadl:doc xmlns="http://www.w3.org/1999/xhtml">
  Upstream file type
  </wadl:doc>
                <wadl:option value="Code Release Tarball"/>
                <wadl:option value="README File"/>
                <wadl:option value="Release Notes"/>
                <wadl:option value="ChangeLog File"/>
                <wadl:option value="Installer file"/>
              </wadl:param>
