Felix Meschberger commented on SLING-2253:
------------------------------------------

Using an expanded patch probably never really worked: The getResource() method 
starts off with normalizing the patch, which just replaces double slashes with 
single slashes. Thus converts 
"/content/test/{http://www.jcp.org/jcr/1.0}content"; to 
"/content/test/{http:/www.jcp.org/jcr/1.0}content" already making the path 
illegal.

Also, if multi workspace resolution would be enabled the URL inside the 
expanded path --- http://.... --- would trigger the path to be assumed to be 
multi workspace indicating http to be the workspace name.

So, all-in-all, it must be said, that at the moment such expanded paths are not 
supported. In addition such paths, IIRC, have not been supported in JCR 1.0 and 
have only been introduced in JCR 2.0.

Theoretically we could add support for expanded paths, in that we check for the 
"/{" substring in the getResource method and specially handle such paths. But 
this would break at least one level of abstraction (one might consider the 
namespace mangling support in the resolve method has the same weakness !). In 
addition I am not sure about the general use of such support....
