 /**
  * Class OC_Connector_Sabre_Server
  *
+ * This class reimplements some methods from @see Sabre_DAV_Server.
+ *
+ * Basically we add handling of depth infinity.
+ *
+ * The right way to handle this would have been to submit a patch to the upstream project
+ * and grab the corresponding version one merged.
+ *
+ * Due to time constrains and the limitations where we don't want to upgrade 3rdparty code in
+ * this stage of the release cycle we did choose this approach.
+ *
+ * For ownCloud 7 we will upgrade SabreDAV and submit the patch - if needed.
