+/// Description:   A generic container for properties defined on
+/// resources.  All elements inside a 'prop' XML element MUST define
+/// properties related to the resource, although possible property
+/// names are in no way limited to those property names defined in
+/// this document or other standards.  This element MUST NOT contain

+///
+/// Purpose:   Groups together a prop and status element that is

+/// Description:   The propstat XML element MUST contain one prop XML
+/// element and one status XML element.  The contents of the prop XML
+/// element MUST only list the names of properties to which the result
+/// in the status element applies.  The optional precondition/
+/// postcondition element and 'responsedescription' text also apply to

+///
+/// Name:   response
+///
+/// Purpose:   Holds a single response describing the effect of a method
+/// on resource and/or its properties.
+///
+/// Description:   The 'href' element contains an HTTP URL pointing to a
+/// WebDAV resource when used in the 'response' container.  A
+/// particular 'href' value MUST NOT appear more than once as the
+/// child of a 'response' XML element under a 'multistatus' XML
+/// element.  This requirement is necessary in order to keep
+/// processing costs for a response to linear time.  Essentially, this
+/// prevents having to search in order to group together all the
+/// responses by 'href'.  There are, however, no requirements
+/// regarding ordering based on 'href' values.  The optional
+/// precondition/postcondition element and 'responsedescription' text
+/// can provide additional information about this resource relative to
+/// the request or result.

+///
+/// Name:   multistatus
+///
+/// Purpose:   Contains multiple response messages.
+///
+/// Description:   The 'responsedescription' element at the top level is
+/// used to provide a general message describing the overarching
+/// nature of the response.  If this value is available, an
+/// application may use it instead of presenting the individual
+/// response descriptions contained within the responses.
