Hi everyone,

I was wondering how I could use <ins> and <del> elements to show
different versions of a document, and thought that it would be useful
to have 'greater than' and 'less than' CSS selectors. Either
specifically for the datetime attribute, or perhaps for any numerical
value.

For example, to highlight (or hide) all the insertions from a
particular point, you could target added comments like this:
<ins datetime="2007-01-16T19:21:49+00:00">Inserted comment</ins>

With:
ins[datetime>="2007-01-15"] {background-color: #ff0;}

I'm sure this must come up for developing specs in HTML quite often,
but I couldn't see anything in the archive?

I realise you could get similar effects dynamically with DOM
scripting, but a CSS selector would allow useful highlighting and
hiding for simple cases, and perhaps people might start using them
more?

Making it a generic selector (e.g. div[class>="10"] ) might be useful
for some things, but I haven't really thought that through. Not very
useful for IDs though, given their restrictions.

Just a thought,

-Alastair
