[wsrp] [change request #237a] Can a CSS class write the label of a button?

In looking back through previous work,
it is clear I was confusing XSLT styling with CSS styling. In XSLT it is
trivial to write the labels for buttons, but appears to not be doable in
CSS. One can use CSS to set a background image, but any label text of the
markup overlays this. Therefore I think either we require Consumers to
set such an image and prohibit Portlets from writing label text for elements
using our control classes (allows the image to contain the relevant words)
or we decide they are not worth defining in v1 as they are more likely
to cause poor UIs than good UIs.
