When looking at the 5.3 component reference for textfield the component parameters are all gone.
I found a few other components and mixins with the same problem while I was in there. I've back fixed this so that it can appear in a 5.3.1 (if we decide to release it as some point).
Integrated in tapestry-trunk-freestyle #631 (See https://builds.apache.org/job/tapestry-trunk-freestyle/631/)
TAP5-1762: Some components do not have include a description of their parameters in their JavaDoc pages
