Subject: Action request: mime-type of xml-dtd should be treated as text

I have a repository with a DTD file checked in and carrying the
property svn:mime-type value application/xml-dtd, the correct
type for it according to RFC 2043. It is inconvenient to do some
Subversion operations on it, such as "blame", because Subversion
thinks it is non-textual. It would be an improvement if XML mime
types were recognised as text, and specifically this one.

As far as I can tell, the enhancement should be to function
svn_mime_type_is_binary in subversion/libsvn_subr/validate.c. I
suggest the following additions to the mime types treated as
text.

application/xml-dtd
application/xml
application/*+xml

(The FAQ and the source agree that Subversion's text mime-types
are text/*, image/x-xbitmap and image/x-xpixmap.)

Do others agree? Should this be entered as a formal SVN issue?

There was a discussion about Subversion's handling of XML files on this
list a few days ago (archived at
http://svn.haxx.se/users/archive-2008-02/0014.shtml) - the consensus
then seemed to be that this behaviour was by design, ie. that XML files
may very well contain binary content
(http://svn.haxx.se/users/archive-2008-02/0017.shtml). The workaround
was to delete the svn:mime-type property, or change it to "text/..."
(http://svn.haxx.se/users/archive-2008-02/0034.shtml).

FWIW I'm not too keen on changing mime-types - "application/xml-dtd" is
a correct mime-type for DTD files. Perhaps there should be an
additional property that specifies text vs. binary, instead of using
mime-type (or eol-style) to guess?

Hope this helps
John
