It looks like ".asx" is currently detected as "video/x-ms-asf". However, it looks like .asf and .asx are very different types of files.

Should we move .asx to, say:

  <mime-type type="application/x-ms-asx">
    <_comment>Windows Media Metafile</_comment>
    <_comment>magic and globs derived from signature in PRONOM</_comment>
    <glob pattern="*.asx"/>
    <magic>
       <match value="<(asx|ASX) (version|Version)" type="regex" offset="0" />
    </magic>
    <sub-class-of type="application/xml"/>
  </mime-type>

Wikipedia claims - https://en.wikipedia.org/wiki/Advanced_Stream_Redirector - that these should have the same mimetype but I think they're wrong...

Shouldn't we do the detection with a xml namespace / tag thing, rather than a regexp magic?

Y. Done. Thank you.

Thank you, Nick Burch!
