Title: xsd renderer - use content type application/xml instead of text/xml

[RFC3023](http://tools.ietf.org/html/rfc3023) states:

> If an XML document -- that is, the unprocessed, source XML document -- is readable by casual users, text/xml is preferable to application/xml. MIME user agents (and web user agents) that do not have explicit support for text/xml will treat it as text/plain, for example, by displaying the XML MIME entity as plain text. Application/xml is preferable when the XML MIME entity is unreadable by casual users.

XSD is definitely not for human consumption, so `application/xml` is a more appropriate content type than `text/xml`.
