LinkRenderer calls writeURIAttribute... but why?

[Jeanne Waldman]

Hi there,

I'm wondering if anyone knows why the links id needs to call 
writeURIAttribute instead of writeAttribute.

The code is in GoLinkRenderer. The comment says that they are URI 
attributes, but it doesn't say why. I have some of my own code that does 
the same thing for links , but it causes a problem if the id is 
non-ascii, like Japanese. I can fix this issue by calling 
writeAttribute, but I don't want to cause other problems that I'm just 
not aware of.
Thanks for any insights!!
