WebDAV: Read resource properties
TElWebDAVClient also has ReadSupportedProperties() method, which is used to retrieve the values of all supported properties
Finally you can use ReadAllProperties() method to perform "DAV:allprop" requests.
The values of the properties will be returned in the instance of TElWebDAVPropertyInfoList, which you need to create and pass to the method. Upon return from the method this instance includes a set of TElWebDAVPropertyInfo objects, each one containing a name and a value of a single property of a remote resource.
