 * just a string of bytes.  The complex interface is 'ne_propfind_*',
 * which is complicated, and hard to use, but lets you parse
 * structured properties, i.e.  properties which have XML content.  */

/* The 'ne_simple_propfind' interface. ***
 *
 * ne_simple_propfind allows you to fetch a set of properties for a
 * single resource, or a tree of resources.  You set the operation
 * going by passing these arguments:
 *
 *  - the session which should be used.
 *  - the URI and the depth of the operation (0, 1, infinite)
 *  - the names of the properties which you want to fetch
 *  - a results callback, and the userdata for the callback.
 *
 * For each resource found, the results callback is called, passing
 * you two things along with the userdata you passed in originally:
 *
 *   - the URI of the resource (const ne_uri *uri)
 *   - the properties results set (const ne_prop_result_set *results)
