java.lang.Object | +--net.sf.saxon.om.NamePool
An object representing a collection of XML names, each containing a Namespace URI,
a Namespace prefix, and a local name; plus a collection of namespaces, each
consisting of a prefix/URI pair.
The equivalence betweem names depends only on the URI and the local name. The prefix is retained for documentary purposes only: it is useful when reconstructing a document to use prefixes that the user is familiar with.
The NamePool eliminates duplicate names if they have the same prefix, uri, and local part. It retains duplicates if they have different prefixes
