Application is most appropriate, and this is why application/xhtml+xml 
is now the MIME type used. text/html was used up until XHTML1.0 which is 
an overlap point - it can be used both with the application/xhtml+xml 
MIME type required for XHTML1.1 and later and the text/html required 
with HTML4.0 and earlier for backwards compatibility (side-note: some 
browsers that react to application/xhtml+xml by considering in a non-XML 
XML document can be made to behave well by assigning an XSLT 
transformation that does an identity transformation - as far as those 
browsers are concerned it received an XML document and then used it to 
produce an HTML document, which coincidentally looks exactly the same as 
the XML document it received :)

Mixed is not for cases like HTML were a document references other items 
which are then mixed together in rendering, but for document types where 
other items are included in the document itself (e.g. a word processor 
document with images embedded into them, rather than linked to from them).
