[css3-mediaqueries] 6.2. width - negative <length> allowed?

I was wondering why a negative <length> for 'width' (and other media features)
is not disallowed. Having the following simple (technically incorrect testcase)
shows hopefully what I mean:

# <html xmlns="http://www.w3.org/1999/xhtml">
#  <style type="text/css">
#   p{ background:red }
#   @media all and (min-width:-100px){ p { background:red  } }
#  </style>
#  <p>This line should have a green background.</p>
# </html>

I hope a further revision of the specification could say that "<length> must be
a positive integer when applied to a media feature specified in this
specification." (Perhaps adding "or zero" to that for clarity if needed.)

Kind regards,

Anne
