PullNamespaceReducer is a PullFilter responsible for removing duplicate namespace
declarations. It also performs namespace fixup: that is, it ensures that the
namespaces used in element and attribute names are all declared.
<p/>
<p>This class is derived from, and contains much common code with, the NamespaceReducer
in the push pipeline. (In the push version, however, namespace fixup is not
performed by the NamespaceReducer, but by the ComplexContentOutputter).</p>

<DD>Get the namespace declarations associated with the current element. This method must
be called only after a START_ELEMENT event has been notified. In the case of a top-level
START_ELEMENT event (that is, an element that either has no parent node, or whose parent
is not included in the sequence being read), the NamespaceDeclarations object returned
will contain a namespace declaration for each namespace that is in-scope for this element
node. In the case of a non-top-level element, the NamespaceDeclarations will contain
a set of namespace declarations and undeclarations, representing the differences between
this element and its parent.
<p/>
<p>This class extends the semantics of the PullProvider interface by allowing this method
to be called also after an END_ELEMENT event. This is to support PullToStax, which requires
this functionality. In this situation it returns the namespaces declared on the startElement
associated with the element that has just ended.</p>
<p>It is permissible for this method to return namespace declarations that are redundant.</p>
<p/>
<p>The NamespaceDeclarations object is guaranteed to remain unchanged until the next START_ELEMENT
event, but may then be overwritten. The object should not be modified by the client.</p>
<p/>
<p>Namespaces may be read before or after reading the attributes of an element,
but must not be read after the first child node has been read, or after calling
one of the methods skipToEnd(), getStringValue(), or getTypedValue().</p>*
