I had presumed from F&O 1.4 that there are four separate fn:abs functions (or at least four separate signatures that are chosen from at compile time). Which parts of the specification imply otherwise? If it is the case that fn:abs has four signatures then the rules given in FS 4.1.5 under "Dynamic Evaluation" deduces four different results for an argument of type xs:integer (since it can be promoted to match any signature). Should this be marked as a bug against Functions & Operators?Received on Friday, 4 April 2008 10:00:15 UTC
