> In the SCA assembly model, there are cases that xpath is used to reference XML segment. For example, policySet's @appliesTo or property's @source. The xpath is declared in the context of the owning document. For example, x:composite/x:component has to be resovled based on the xmlns:x declaration in the owning document. When the xpath is applied to another document which has different prefix/namespace mapping, it's broken. One of the solution is to pass the compiled version of the xpath expression (javax.xpath.XPathExpression) instead of the raw string.
> To reproduce the problem, change the Calculator.composite file in the sample-calculator-impl-policies module to remove the xmlns:sca declaration which is not required at all in the composite document.
