New Comment:
You can run DOMs through an XSLT identity transform to strip redundant
namespaces, since this removes (what it deems to be) unused namespaces
(i.e. namespaces which don't appear as elements or attributes).
This method is not only slow for large DOMs, if you're working with
XSDs or XSLTs, both of which use namespaces inside attribute values, it
would need modification, since XSLT strips them.

Description:
------------
There seems to be no good way of manipulating XML namespace
declarations at all. In particular, they never get garbage collected in
any way, and you cannot remove them manually, so they will stick around
forever unless you create a new one. My typical use case is shown in the
reproduce code below (although the element will typically have child
elements).
Since 5.3 (bug #38949) it seems I can getAttribute() the xmlns element,
but still not remove it it any reasonable way (and it should really just
disappear by itself; it does in other languages).
Reproduce code:
---------------
<?php
$doc = new DOMDocument;
$doc->loadXML('<html xmlns="something"><element xmlns:ns="whatever"
ns:foo="bar" /></html>');
$root = $doc->documentElement;
$elem = $root->firstChild;
$elem->removeAttributeNode($elem->attributes->item(0));
print $doc->saveXML();
?>
Expected result:
----------------
<?xml version="1.0"?>
<html xmlns="something"><element/></html>
Actual result:
--------------
<?xml version="1.0"?>
<html xmlns="something"><element xmlns:ns="whatever"/></html>
