+ ///
+ /// Purpose: Contains the Last-Modified header value (from Section
+ /// 14.29 of [RFC2616]) as it would be returned by a GET method
+ /// without accept headers.
+ ///
+ /// Value: rfc1123-date (defined in Section 3.3.1 of [RFC2616])
+ ///
+ /// Protected: SHOULD be protected because some clients may rely on the
+ /// value for appropriate caching behavior, or on the value of the
+ /// Last-Modified header to which this property is linked.
+ ///
+ /// COPY/MOVE behavior: This property value is dependent on the last
+ /// modified date of the destination resource, not the value of the
+ /// property on the source resource. Note that some server
+ /// implementations use the file system date modified value for the
+ /// DAV:getlastmodified value, and this can be preserved in a MOVE
+ /// even when the HTTP Last-Modified value SHOULD change. Note that
+ /// since [RFC2616] requires clients to use ETags where provided, a
+ /// server implementing ETags can count on clients using a much better
+ /// mechanism than modification dates for offline synchronization or
+ /// cache control. Also note the considerations in Section 8.8.
+ ///
+ /// Description: The last-modified date on a resource SHOULD only
+ /// reflect changes in the body (the GET responses) of the resource.
+ /// A change in a property only SHOULD NOT cause the last-modified
+ /// date to change, because clients MAY rely on the last-modified date
+ /// to know when to overwrite the existing body. The DAV:
+ /// getlastmodified property MUST be defined on any DAV-compliant
+ /// resource that returns the Last-Modified header in response to a
+ /// GET.
+ ///
+ /// <!ELEMENT getlastmodified (#PCDATA) >

+
+ /// 15.8. lockdiscovery Property
+ ///
+ /// Name: lockdiscovery
+ ///
+ /// Purpose: Describes the active locks on a resource
+ ///
+ /// Protected: MUST be protected. Clients change the list of locks
+ /// through LOCK and UNLOCK, not through PROPPATCH.
+ ///
+ /// COPY/MOVE behavior: The value of this property depends on the lock
+ /// state of the destination, not on the locks of the source resource.
+ /// Recall that locks are not moved in a MOVE operation.
+ ///
+ /// Description: Returns a listing of who has a lock, what type of lock
+ /// he has, the timeout type and the time remaining on the timeout,
+ /// and the associated lock token. Owner information MAY be omitted
+ /// if it is considered sensitive. If there are no locks, but the
+ /// server supports locks, the property will be present but contain
+ /// zero 'activelock' elements. If there are one or more locks, an
+ /// 'activelock' element appears for each lock on the resource. This
+ /// property is NOT lockable with respect to write locks (Section 7).
+ ///
+ /// <!ELEMENT lockdiscovery (activelock)* >
+ LockDiscovery(Vec<ActiveLock>),

+
+ /// 15.9. resourcetype Property
+ ///
+ /// Name: resourcetype
+ ///
+ /// Purpose: Specifies the nature of the resource.
+ ///
+ /// Protected: SHOULD be protected. Resource type is generally decided
+ /// through the operation creating the resource (MKCOL vs PUT), not by
+ /// PROPPATCH.
+ ///
+ /// COPY/MOVE behavior: Generally a COPY/MOVE of a resource results in
+ /// the same type of resource at the destination.
+ ///
+ /// Description: MUST be defined on all DAV-compliant resources. Each
+ /// child element identifies a specific type the resource belongs to,
+ /// such as 'collection', which is the only resource type defined by
+ /// this specification (see Section 14.3). If the element contains
+ /// the 'collection' child element plus additional unrecognized
+ /// elements, it should generally be treated as a collection. If the
+ /// element contains no recognized child elements, it should be
+ /// treated as a non-collection resource. The default value is empty.
+ /// This element MUST NOT contain text or mixed content. Any custom
+ /// child element is considered to be an identifier for a resource
+ /// type.
+ ///
+ /// Example: (fictional example to show extensibility)
+ ///
+ /// <x:resourcetype xmlns:x="DAV:">
+ /// <x:collection/>
+ /// <f:search-results xmlns:f="http://www.example.com/ns"/>
+ /// </x:resourcetype>
+ ResourceType(Vec<ResourceType<E>>),
+
+ /// 15.10. supportedlock Property
+ ///
+ /// Name: supportedlock
+ ///
+ /// Purpose: To provide a listing of the lock capabilities supported by
+ /// the resource.
+ ///
+ /// Protected: MUST be protected. Servers, not clients, determine what
+ /// lock mechanisms are supported.
+ /// COPY/MOVE behavior: This property value is dependent on the kind of
+ /// locks supported at the destination, not on the value of the
+ /// property at the source resource. Servers attempting to COPY to a
+ /// destination should not attempt to set this property at the
+ /// destination.
+ ///
+ /// Description: Returns a listing of the combinations of scope and
+ /// access types that may be specified in a lock request on the
+ /// resource. Note that the actual contents are themselves controlled
+ /// by access controls, so a server is not required to provide
+ /// information the client is not authorized to see. This property is
+ /// NOT lockable with respect to write locks (Section 7).
