/**
* This class keeps track of the currently defined namespaces. Conceptually the
* prefix/uri/depth triplets are pushed on a stack pushed on a stack. The depth
* indicates the nesting depth of the element for which the mapping was made.
*
* <p>For example:
* <pre>
* <chapter xmlns:p1="def">
* <paragraph xmlns:p2="ghi">
* <sentance xmlns:p3="jkl">
* </sentance>
* </paragraph>
* <paragraph xlmns:p4="mno">
* </paragraph>
* </chapter>
* </pre>
*
* When the <chapter> element is encounted the prefix "p1" associated with uri
* "def" is pushed on the stack with depth 1.
* When the first <paragraph> is encountered "p2" and "ghi" are pushed with
* depth 2.
* When the <sentance> is encountered "p3" and "jkl" are pushed with depth 3.
* When </sentance> occurs the popNamespaces(3) will pop "p3"/"jkl" off the
* stack. Of course popNamespaces(2) would pop anything with depth 2 or
* greater.
*
* So prefix/uri pairs are pushed and poped off the stack as elements are
* processed. At any given moment of processing the currently visible prefixes
* are on the stack and a prefix can be found given a uri, or a uri can be found
* given a prefix.
*
* This class is public only because it is used by Xalan. It is not a public API
