Ok.

I notice that you decided against adding tags around function and type 
names.

I understood that. I think that the likelyhood of someone removing the 
section about rounding in the IEEE standard is very low, and the current 
php link is pretty ugly from a REST perspective, and would prevent to see 
the possible improved version of the page. Well, no big deal.

I'm afraid that the current implicit rule is more or less "no links", at 
least there are very few of them but in the glossary, and when I submitted 
docs with them they were removed before committing.

However I do support the idea that these links are useful references and 
should be put where appropriate, even if it means that there must be some 
updates from time to time.
