Seems reasonable...

(But raises a little warning bell in my head  -what does it mean to  be
marked up to indicate something will cost money? does it means conforms to
the W3C micropayments draft? Or conforrms to some other XML language for
identifying transactions? or conforms to the published house style of some
commerce outfit, who produce metadat that identifies every link that costs
money? I think we need implementation experience to answer this one - maybe
we should ask the people who worked on commerce at W3C, and other people who
are doing so...)
