    Assumptions in the above statement:

1) The legacy UA supports CSS, specifically the "display" property.

2) The webmaster knows CSS in addition to HTML4 + WA1.

3) The legacy UA doesn't have a CSS document that overrides the web 
page's CSS with regards to unknown tags.

4) The browser supports styling of unknown elements without some kind of 
markup hack or the use of something like an HTC.

    Furthermore, all our "gracefully degradation" solutions so far have 
not required CSS.
