Our current model in that we are thinking of putting into the widget
packaging spec is:

1. match the file extension to a mime type using the extension to MIME
type tables in the packaging spec.
2. if no match is made, then attempt to sniff the mime type.
3. if no match is made, label the file 'unknown/unknown'.

What we could do is add a step 0, where authors could have an
XML-based (or text based) format for declaring extension to MIME
(e.g., php -> text/html) or overriding default extensions to MIME
mappings.

For example,
<types xmlns="http://www.w3.org/ns/widgets">
  <type ext="php" mime="text/html"/>
  <type ext="jsp" mime="text/html"/>
  <type ext="htm" mime="application/xhtml+xml"/>
</types>

The above elements could either just be part of the configuration
document, or could be in a separate file.

probably true.
