Table 8 — XACML MRP response example
Processing of the AD above has the effect that the PEP removes that XML element from the CSW response, which is referenced by the following xpath expression:
[local-name=OWSContext][1][local-name=ResourceList][1][local- name=Layer][1]
This XML element actually represents the following resource listing in the OWS Context document:
?xml version=1.0 encoding=UTF-8?
