only relevant while parsing u-photo; p-photo will pick up the alt and not the url anyway.

Major change so for version 2.0.0 (if it goes into spec). Put under a flag for now alt_in_photo ?

@snarfed any "better" suggestions for the flag name?

[snarfed]

thanks! nah, i'm agreeable.

[snarfed]

however, i'd strongly encourage standardizing on microformats/mf2py for issues and turn them off here. 😄 tracking issues across multiple repos is a recipe for confusion and skew.

@snarfed yes the actual issues on the main repo are the "real" ones. These are just for my notes and memory since it seems right now I am the only one actively coding this thing!

[snarfed]

right, i understand...but they're still public, and some are duplicated, and some will skew, all of which confuses readers.

take notes for memory on the main repo issues! totally appropriate. notes are useful for other people too, collaboration and all. no one will complain. 😁
