Thanks, I can see clearer now.

I agree that [mod://...#deeplink] is broken, (why on hell is the # escaped ?)

I didn't see that before (also partly b/c my nodelet hack automatically redirected them)

But beside the broken PM-tag are deep-links to headings quite consistent ( seems only whitespace in anchors is - here and _ there)

Talking about deep-links to items ...

... well I ignored their existence. Never seen them used and I agree with tobyinc to avoid them b/c of inconsistencies.

In CPAN you need to read the source to find them, cause they are not indexed in the TOC. So almost nobody would link them.

METACPAN has a CSS trick to show those hidden anchors on mouseover. AND I agree that the naming scheme is not very reliable. BUT this should only be a problem when translating from META to CPAN.

So in short, "secret" deep-links should be avoided anyway and translating heading-anchors shouldn't be a problem, but the [mod://] markup is broken anyway.
