This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
The spec now uses * #ltimage for <image> * #ltgradient for <gradient> * #ltelment-refererence for <element-reference> and so on as compared to, say, css3-text which uses #spacing-limit for <spacing-limit>. (Although, there something equivalently bad: #ltbg-imagegt for <bg-image> in css3-background.) There's apparently nothing really harmful here except I think it's ugly.
Fixed all the places I could find (found via a /dfn></ regex). Let me know if there are any left that I missed.
