/**
* The Name Space Manager tracks the association between a NameSpace
* URI and the PRInt32 runtime id. Mappings between NameSpaces and
* NameSpace prefixes are managed by nsINameSpaces.
*
* All NameSpace URIs are stored in a global table so that IDs are
* consistent accross the app. NameSpace IDs are only consistent at runtime
* ie: they are not guaranteed to be consistent accross app sessions.
*
* The nsINameSpaceManager needs to have a live reference for as long as
* the NameSpace IDs are needed.
