[css21] Initial containing block definition (editorial)

Section 10.1 says:
The containing block in which the root element<file:///C:/Users/Grant/Documents/aWork/W3C/CSS/2.1/conform.html#root> lives is a rectangle with the dimensions of the viewport<file:///C:/Users/Grant/Documents/aWork/W3C/CSS/2.1/visuren.html#viewport>, anchored at the canvas origin for continuous media, and the page area for paged media. This containing block is called the initial containing block.

This wording seems to allow the interpretation that the page area has the dimensions of the viewport.  I suggest rewording to:
The containing block in which the root element<file:///C:/Users/Grant/Documents/aWork/W3C/CSS/2.1/conform.html#root> lives is a rectangle called the initial containing block.  For continuous media, it has the dimensions of the viewport<file:///C:/Users/Grant/Documents/aWork/W3C/CSS/2.1/visuren.html#viewport>, and is anchored at the canvas origin; it is the page area for paged media.

I also suggest 'page area' link to its definition in Section 13.2.

Best wishes,

Melinda
