Move the namespace normaliser for normal UK federation metadata into …

…the mdx/uk directory. Duplicate it as ns_norm_test and use that as the namespace normaliser for the test aggregate. This will allow the test aggregate to have its own normalisation rules.

+	ns_norm_test.xsl
+	
+	Normalise the namespaces in the UK federation's test aggregate.
+	
+	The main constraint on the output of this transform is that it should minimise the size
+	of the output file while not having "too many" namespace prefix definitions in scope
+	at any point in the document.  "Too many" is more than about ten, as a result of a bug
+	in the metadatatool application used by Shibboleth 1.3 IdPs to download and verify
+	metadata.
+	
+	The strategy is to define the most commonly-used prefixes in the document element.
+	
+	Prefixes which are less often used, but which may be used by container elements
+	(e.g., mdui:) or for attributes are normalised to use a prefix, but not declared
+	on the document element.
+	
+	Prefixes which are less often used and are only used for non-containers can be
+	normalised to non-prefix use (i.e., to redefine the default namespace) if required
+	to cut the numbers down.
