|
* The Name Space Manager tracks the association between a NameSpace
|
|
* URI and the int32_t 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 nsNameSpaceManager needs to have a live reference for as long as
|
|
* the NameSpace IDs are needed.
