There are a large number of non-textual XML files under:

http://ala.vsms.nottingham.ac.uk/vsms/java/jumbo/cml12/cml/

most of them served from APPLETs, but you can get the *.xml from the HTML
source.

Thanks for this reminder. For Chemical Markup Language Henry and I had
originally devised our own MIME type (not official) : chemical/x-cml. But,
with the likely introduction of other namespaces (e.g. RDF:*, MathML) in
CML documents, it is clear that there is no need for diversity, since the
namespaces themselves will have means of identifying the XML application.
So CML documents will be "text/xml", unless we should use "application/xml"
instead.

<IGNORANCE>
What will differentiate a text/xml document from an application/xml one?
