the functions should do it ,.. 
which spec are you speaking of ? 

public void accumulate(Serializable context , Object request) {
		List<ResourceMatch> counts = (List<ResourceMatch>) context;
		RequestCtx xacml = (RequestCtx) request;
		for (Iterator<Attribute> iterator = xacml.getResourceAsList().iterator();
iterator.hasNext();) {
			Attribute resource = (Attribute) iterator.next();
			if (counts.size() == 0 &&
resource.getId().toString().equalsIgnoreCase("urn:oasis:names:tc:xacml:1.0:resource:resource-id"))
{
				try {
					counts.add(new ResourceMatch(new
URI(DroolsUtils.getAttributeIDValue(resource)),0));
				} catch (URISyntaxException e) {
					// shouldnt appear cause the method from DroolsUtils has casted the
returning String from an URI!
					e.printStackTrace();
				}
			}

			for (int i = 0; i < counts.size(); i++) {
				
				ResourceMatch resourcematch = counts.get(i);
				try {
					if (resourcematch.matches(new
URI(DroolsUtils.getAttributeIDValue(resource)))
							&&
resource.getId().toString().equalsIgnoreCase("urn:oasis:names:tc:xacml:1.0:resource:resource-id")
) {
						resourcematch.increment();
					}else if (counts.size() == i-1 &&
resource.getId().toString().equalsIgnoreCase("urn:oasis:names:tc:xacml:1.0:resource:resource-id"))
{
						counts.add(new ResourceMatch(new
URI(DroolsUtils.getAttributeIDValue(resource)),1));
					}
				} catch (URISyntaxException e) {
					// shouldnt appear cause the method from DroolsUtils has casted the
returning String from an URI!
					e.printStackTrace();
				}
			}
		}
	}
