Oh yes, I overlooked  the possibility of using XPointer as fragment 
selector. I am currently not quite sure if it is allowed to be used with 
URNs too(we can not use URLs to identify data records in or use case), 
but at a first glance, it looks that the standard does not forbid that. 
So, I don't need to define a XPath Selector anymore. Good News.

Hmm, I know that my use case is not quite typical as all recent 
discussions went around that image in a web page example. That's why I 
am asking to the list, if it would be "forbidden" to use oa:hasScope in 
the way I described ?
So, can I use oa:hasScope within a Specific Body  to point at the 
(resolvable)URI of a Specific Target, which defines somehow the context 
in which the scoped body content should be seen by a client (application) ?

May be a short example:
Lets have a XML-document urn:uuid:doc01 as source. In my annotation I 
define 2 Specific Targets aggregated in a Composite, 
urn:uuid:doc01#xpointer(/a) and urn:uuid:doc01#xpointer(/b).
Now I have two Specific Bodies also aggregated in a composite, one is 
holding contentAsText:"aaa", the other "bbb" and I want that the one 
holding "aaa" should only be applied in context with Specific Target 
urn:uuid:doc01#xpointer(/a) , the one holding "bbb" only with Specific 
Target urn:uuid:doc01#xpointer(/b).
Finally, I want to add property "oa:hasScope 
urn:uuid:doc01#xpointer(/a)" to Specific Body "aaa" and "oa:hasScope 
urn:uuid:doc01#xpointer(/b)" to Specific Body "bbb" in order to express 
this with OA 1.0.
Is this possible ?

Lutz
