- Added XMLUtils#SAXBasedXmlnsFilteringParser constructor with XML namespace prefix-to-URI mappings to help fix issue authzforce/server#66

- Bugfix: reusing the same XPathCompiler for multiple calls to compile(String) method on XPaths with XPath variables changes the internal state, has same effect as calling declareVariable(QName)without reinitializing, i.e. variables add up.

- Added XPathCompilerProxy interface method to get the list of all variables allowed in input XPath expressions: List<VariableReference<?>> getAllowedVariables();
- Added immutable implementation of BaseXPathCompilerProxy: BasixImmutableXPathCompilerProxy
- Added support for XACML Policy Variables as XPath variables in xpathExpression AttributeValues

- Added feature: possibility to use XACML Variable references as XPath variables in AttributeSelector/AttributeValue's XPath expressions
- Added XdmItem getXdmItem() to all PrimitiveValues and getXdmValue() to all Value implementations in order to provide the XdmItem value of XPath variables in XPath expressions
- New class XPathCompilerProxy to make a immutable version of XPathCompiler and add extra methods such as getDeclaredNamespacePrefixToUriMap() to help create new XPathCompilers based on XPathCompilerProxy
- Refactoring: replaced SAXON XPathCompiler with immutable wrapper class XPathCompilerProxy in API methods for safer code, and to fix Spotbugs issues
- Changed AttributeValueFactory extension's interface:
getInstance() arg XPathCompiler (Saxon) replaced with Optional<XPathCompilerProxy>
- Changed Datatype interface: added ItemType getXPathItemType() used to declare Variable types on XPathCompiler when compiling XPath expressions using VariableReferences
- Changed EvaluationContext interface:
  - Added getVariables() to get list of all VariableReferences/Values in context for evaluation of XPath expression (using XACML variables as XPath variables)
  - putVariableIfAbsent(String variableId,...) replaced with (VariableReference variableRef,...)
 - Changed ExpressionFactory interface: added isXpathEnabled() and getVariableExpressions() to get list of VariableExpressions() for declaring all Variable names/types on XPath expression (using XACML Variables as XPath variables) compiler
 - Changed VariableReference interface: added getXPathVariableName() -> QName to assign variables when evaluating XPath with SAXON XPathCompiler
