rest - What's the difference between text/xml vs application/xml for webservice response

Question

This is more of a general question about the difference between text/xml and application/xml. I am fairly new to writing webservices (REST - Jersey). I have been producing application/xml since it is what shows up in most tutorials / code examples that I have been using to learn, but I recently found out about text/xml and was wondering what is different about it and when would you use it over application/xml?

Answer 1

From the RFC (3023), under section 3, XML Media Types:

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.
