Well, I'd have thought _you_ would have schema validated your input:-)
In which case, assuming @days is of the appropriate sequence type, the
typed value of the attribute as seen by xpath will alr4eady be a
sequence of dayTimeDurations and you do not have to do anything.
If you do want to tokenize and cast, just apply the cast to teh sequence
<xsl:variable name="ds" select="for $d in tokenize(@day,'\s+') return
xs:dayTimeDuration($d)"/>
(tokenize(//topics/@days would generate an error if it picked up two
attributes)
