    `java.lang.String` | `getSchemeData()` Returns a String containing the scheme data of the PointerPart.
    `java.lang.String` | `getSchemeName()` Returns a String containing the scheme name of the PointerPart or the name of the ShortHand Pointer.
    `boolean` | `isChildFragmentResolved()` Returns true if the XPointer expression resolves to a non-element child of the current resource fragment.
    `boolean` | `isFragmentResolved()` Returns true if the XPointer expression resolves to a resource fragment specified as input else returns false.
    `void` | `parseXPointer(java.lang.String part)` Provides scheme specific parsing of a XPointer expression i.e.

    - #### parseXPointer

          void parseXPointer(java.lang.String part)
                      throws org.apache.xerces.xni.XNIException

      Provides scheme specific parsing of a XPointer expression i.e. the PointerPart or ShortHandPointer.
      Parameters:
        `part` - A String representing the PointerPart or ShortHandPointer.
      Throws:
        `org.apache.xerces.xni.XNIException` - Thrown if the PointerPart string does not conform to the syntax defined by its scheme.

    - #### resolveXPointer

          boolean resolveXPointer(org.apache.xerces.xni.QName element,
                                  org.apache.xerces.xni.XMLAttributes attributes,

                           throws org.apache.xerces.xni.XNIException

      Evaluates an XML resource with respect to an XPointer expressions by checking if it's element and attributes parameters match the criteria specified in the xpointer expression.
      Parameters:
        `element` - - The name of the element.
        `attributes` - - The element attributes.
        `augs` - - Additional information that may include infoset augmentations
        `event` - - An integer indicating 0 - The start of an element 1 - The end of an element 2 - An empty element call
      Throws:
        `org.apache.xerces.xni.XNIException` - Thrown to signal an error
