--- Comment #4 from Mathias Bynens <mathias@qiwi.be> 2012-02-15 20:02:47 UTC ---
Pardon my ignorance, but what’s the harm in adding `textarea@pattern`? Several
valid use cases have been presented in comment #1 and comment #2.
FWIW, I just ran into some more cases where `textarea@pattern` would’ve been
very welcome:
* validating binary input in groups of 8 bits: `pattern="([01]{8})*"`
* extended ASCII input: `pattern="[\x00-\xff]*"`
I needed these for a purely client-side web app:
http://mothereff.in/binary-ascii I ended up manually validating the value
through JavaScript, adding `class=invalid` to <textarea>s with invalid input.
