Description Michael Kay 2005-07-13 15:11:20 UTC 
In 10.8.11 op:subtract-dayTimeDuration-from-date we read:

 If $arg2 is negative, then the xs:date returned precedes $arg1.

This should say

 If $arg2 is positive, then the xs:date returned precedes $arg1.

The same error occurs for other permutations of subtract-XX-duration-from-date|time

Closing bug because commenter has not objected to the resolution posted and more than two weeks have passed.
