/**

|
* The Name Space Manager tracks the associtation 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.
|
|
*
|
|
* To create a stack of NameSpaces, call CreateRootNameSpace, and then create
|
|
* child NameSpaces from the root.
