I think we only have two kinds of links in paragraph <a> tags

1) internal jumps

2) external links

We cannot check 1 at parse time because the target is not generally expected to 
exist at parse time and even if the jump is backwards the target may or may not 
have been processed into a findable form at the time of parsing.

We cannot check 2 at parse time because it is not expected to be executable 
except by a document reader ie we're several layers away from executing the link 
in a suitable environment.
