Possible Names for the "supports" token for PFE

At today's meeting we discussed some possible names that might be used for
the "supports" token in CSS @font-face when specifying a URL which supports
progressive font enrichment. For those who haven't seen the supports syntax
before:

@font-face {
  ...
  src: url(myfont.ttf) format(truetype supports <technology>);
}

Here's the list of names for <technology> that were mentioned at today's
meeting, along with my thoughts on them:

   - incremental
      - My current favourite, describes pretty well what will be happening.
   - progressive
      - Draws parallels to progressively loaded images, however may have
      the incorrect connotation that you get a less good very of the font at
      first which is later improved upon.
   - streaming
      - Possibly implies that the transferred font is not retained between
      uses. Also streaming doesn't quite correctly describe the operation of
      patch/subset. Though it does work well for range request.
   - augmentation
      - This potentially has the same issues as progressive.
   - enrichment
      - This potentially has the same issues as progressive.
   - partial
      - This potentially has the same issues as progressive.

What are your thoughts? Also please add other ideas for possible names to
this thread if you have any additional ones.
