Yes, exactly.

Yes, I have seen several of them. Some of them are already open-sourced.
For example there is Drupal module (https://drupal.org/project/its)
which uses custom jQuery plugin to easily access all ITS metadata
directly within browser (http://plugins.jquery.com/its-parser/). However
because Selectors are not yet capable of accessing attributes this
jQuery ITS plugin currently supports only ITS rules based on XPath via
document.evaluate().

Indeed, sorry if I was too terse. But from your previous emails I got
impression that you understand to ITS use-case but you don't consider it
strong enough to extend Selectors.

Have a nice day,
