  - ### push

    public void push()

  - ### pop

    public void pop()
    Leave a scope: this removes any NS declarations that were added in the last scope. Note that I don't bother to validate that you don't call popScope too many times; that's your problem.

  - ### add

    public void add(String prefix, String uri)
    Add a new declaration to the current scope. This is visible within the current scope as well as from any nested scopes.
    Parameters:
      `prefix` - the prefix to be used for this namespace
      `uri` - the namespace name of this namespace.

  - ### add

    public String add(String uri)
    Add a new declaration to the current scope using a unique prefix and return the prefix. This is useful when one just wants to add a decl and doesn't want to have to deal with creating unique prefixes. If the namespace name is already declared and in scope, then the previously declared prefix is returned.
    Parameters:
      `uri` - the namespace name of this namespace
    Returns:
      the unique prefix created or previously declared for this namespace

  - ### getPrefix

    public String getPrefix(String uri)
    Return the prefix associated with the given namespace name by looking thru all the namespace declarations that are in scope.
    Parameters:
      `uri` - the namespace name for whom a declared prefix is desired
    Returns:
      the prefix or null if namespace name not found

  - ### getURI

    public String getURI(String prefix)
    Return the namespace name associated with the given prefix by looking thru all the namespace declarations that are in scope.
    Parameters:
      `prefix` - the prefix for whom a declared namespace name is desired
    Returns:
      the namespace name or null if prefix not found
