The location is a fully qualified name that
indicates the position of the expression in the rule hierarchy. It has the
form
identifier.identifier....,
where each occurrence of
identifier is one of the following:
- The value of the name attribute for an XML element that is in the respective
hierarchy.
- For elements that occur multiple times in a rule block or rule and have
no name attribute: the XML element that contains the expression, followed
by an index number in brackets. This index number indicates the position of
the expression within its containing element. The counter for assigning index
numbers begins with 0 rather than 1. Therefore, if an element is contained
within the third <action> element, for example, the index number is shown
as action[2].
These identifiers are in descending order from the highest level rule
block to the lowest level element that contains the expression.
