URL/URI Normalization

[Nathan]

I'm currently trying to find any text in the HTML specifications which 
give an indication on which steps of URL (/URI) normalization should, or 
should not, be followed by implementations.

I threw together a quick test page at http://webr3.org/urinorm/html and 
have found all browsers (which I've tested) do some of the URI 
normalization steps, with only chrome and IE doing full normalization.

Any pointers or consideration to this would be greatly appreciated, 
unsure if it's an "issue" or not for the specification(s).

Best,

Nathan
