+/**
+ * Invokes a hook to any dependent modules asking them if their installations require
+ * any fedora objects to be present. Modules implementing this hook should return an array
+ * of arrays of the form:
+ *
+ * array( 'pid', 'path-to-foxml-file', 'dsid', 'path-to-datastream-file', int dsversion)
+ *
+ * where the last three options are optional. A module can either point to a simple
+ * foxml file to install, or can specify a datastreamstream to check for, with a
+ * path to load the datastream from if it isn't there. Optionally a version number
+ * can be included, to enable updating of content model or collection policy streams
+ * that may have been updated. THis is a simple whole number that should be incremented
+ * when changed.  This value appears in as an attribute of the topmost element of the stream,
+ * e.g.,:
+ *
+ * <?xml version="1.0" encoding="utf-8"?> <content_model name="Collection" version="2" ...
+ *
+ * Datastreams which don't have this element are assumed to be at version 0.
