James,

I second and support your proposal.

Actual content [1]:
"
The width of a replaced element's box is intrinsic and may be scaled by
the user agent if the value of this property is different than 'auto'. "

Proposed change:
"
The width of a replaced element's box is intrinsic and should be scaled by
the user agent if the value of this property is different than 'auto'. "
