The module http://drupal.org/project/xml_views was created during gci by dmitrig01 but it needs some kind of documentation.
So first you have to get familiar with the module. Once you are ready you should write the advanced help html in the /help directory which describes the user what to do.

Some use cases which could be described in the help:

* Get a xml file from http://developer.yahoo.com/yql/console/ and build a view based on this
* Use another custom xml file

Once you have build the views you could provide them as default views for the module

Deliverable

* A patch/commit against the module
