InCommon metadata support

["Schwoerer, Bradley J" <>]

I was reworking our local metadata file generation script and part of it was 
to do some xml tidy type tasks.  As I was working through the generation of 
our local file, I had decided to use the incommon federation metadata file as 
a sanity check.   After comparing the input and output files for the incommon 
metadata, I did notice an almost 500KB (7% reduction) in file size.   This 
was mostly from just doing all of the xmlns:* declarations at the 
EntitiesDescriptor node and removing all of the duplicates declarations.  
Just because it piqued my interest, I was looking to see if I could do 
further reduction.  With removing the two spaces used for indention and just 
leaving the newline, it reduced it another 500KB.

I am not sure how many times per day the metadata file is downloaded, but I 
thought I would bring it to someones attention of the potential savings in 
bandwidth by making a few changes to the generated metadata file.
