Jangle connector feed or search responses can include URLs to XSLT stylesheets to be applied at either the "feed" level or the "entry/content" level. Jangle does not define which version of XSLT is permissible, but developers should not assume all Jangle core implementations can support XSLT 2.0.
The stylesheet URLs must be accessible to the Jangle core via HTTP.
"Feed" level stylesheets (which is sent in JSON as an array) are to be applied after the connector response has been serialized as an Atom Syndication Format feed. The stylesheets are applied serially, in the order they appear in the array.
Resource level stylesheets can be applied at any time, since they should transform the data in the atom:entry/content tag as an independent document, not as a child element in the Atom feed.
The stylesheets should not transform the Atom into another format, although they can be used to set the values of the Atom elements or provide Atom extensions.
