and some other cleanups: Add XMPPIMAGESURL. Use multiple target rule for
"mkdir -p". Use special variables where possible. Remove unnecessary [

* Recast the document to match the registration procedure defined by XEP-0166 for new application types.
* Explicitly defined the schema of the <file/> element instead of referencing XEP-0096.
* Defined the use of a 'length' attribute on <range/> elements. This attribute was always there because the <file/> and <range/> elements had been defined as the same as the parallel elements in XEP-0096, but the 'length' attribute was not explicitly referenced in this document.
* Clarified the need for the 'senders' attribute on Jingle <content/> elements to distinguish between File Offers and File Requests.
* Added the <file-not-found/> and <file-too-large/> reason types.
* Clarified how to abort a file transfer via 'content-remove' or 'session-terminate' actions.
* Added <received/> element for indicating that a transfer was successful, particularly when there are multiple transfers.
* Added SDP mapping.

After discussion on the standards list at the time of Last Call, it

discrepancies, and to try to reflect general consensus between
implementations of what should be eligible for carbons delivery.
