Under 8.5.4 Border shorthand properties:
http://www.w3.org/TR/CSS21/box.html#border-shorthand-properties
percentage values are mention explicitly.
'Percentages: N/A'
Which is not the most clear formulation.
I think that this should be understood as 'does not apply' or
'undefined', as far as CSS 2.1 is concerned.
CSS3 border module is more explicit:
'Percentages: width* of containing block'
<http://www.w3.org/TR/css3-border/#the-border-width>
The width of the border should be computed based on the width of the
box, the same way as percentage based margins are computed.
