question re tts:display test

i'm writing tests for tts:display, and would like to make them simpler than the one shown in the spec ( http://www.w3.org/TR/2006/CR-ttaf1-dfxp-20061116/#style-attribute-display).  before i get too carried away, i thought i'd send one sample.  does this look correct?

thanks.
