The given string matches the xs:duration pattern (PnYnMnDTnHnMnS, last n may be a fraction). The restriction is specified to be: "[^YM]*[DT].*" My mad regular expression skills and sed tell me, this is a legal value for that restriction: # echo PDT3H2M10.001S | sed -e 's|[^YM]*[DT].*|Matched!|' Matched! 11104 1 mike 2006-08-13 14:21:40 +0000 The pattern facet restriction "[^YM]*[DT].*" is saying "if the lexical value is valid for xs:duration and matches "[^YM]*[DT].*", then it is valid for xs:dayTimeDuration". Or to put it another way "a duration is a valid dayTimeDuration if it contains a D or a T that isn't preceded by a Y or an M." PDT3H2M10.001S is not valid in the lexical space of xs:duration, so it's irrelevant whether it matches the restricted pattern or not. Michael Kay personal response 11105 2 martin 2006-08-13 14:29:27 +0000 I get it. Thanks for the explanation, I didn't pay attention to the fact that xs:duration always requires a Y component.
