Blocking via an attribute

would it be possible to have an attribute that blocks an element, for example it could look like so:

<div block-ui="i-block" block-ui-reason="{reason}">..</div>

If reason is set to null then the blocking won't occur, but if it's a string then it blocks and displays the string.

This would clean up wherever I use block UI quite a lot.
