w3 validation
I noticed something about non unique id's like in issue #1455 mentioned. There are however a lot of warnings, some errors and advises when I check my instance with the w3 validator.
Partly this can be fixed in the tpl files by simply remove trailing slashes but there are some places that are not logical for me.
Is there some kind of agreement to what hubzilla should validate? Plain html? xhtml? When someone wants to fix that it should be clear what the wished end result should be imho
