-<!-- 
-"sfa-input" specifies the subset of the requestor context that this match needs to see. It is specified as an xpath expression.
-For this simple match, we just need to look at sfa-input. 
-
-"rule" specifies an xpath/xquery expression that evaluates the match. In this case, we just check if the requestor's HRN is the same
-as the one matched by this rule.
