Can I suggest instead we use the more W3-like "content" property instead:

http://www.w3.org/TR/CSS2/generate.html#content

which would be Less Astonishing for non-OSMers when they encounter it.

So instead you'd have :

  way[highway] { content: tag('name'); }
  area[amenity=toilet] { content: "WC"; }

This has the advantages:

1) People new to MapCSS will still recognise it when they see it
2) Existing CSS parsers will need less hacking to recognise it
3) It can be used for more types of content than just text

Thoughts?
