Do syntax definitions permit bold/italic/underline coloring/styling?

[Sebastian Gniazdowski <sgniazdowski gmail com>]

Hi,
I've tried appending the style like it works for theme files, ie.:

    keyword whole case color227;;bold+italic

However the keyword "case" is drawn with black color. Grepping for
"bold" in syntax/ yields empty result. So it seems that it's not
possible to apply the styles in syntax coloring?
