Question about getPointAtLength

Hi,
        I would like inquire about the desired behavior of the 
getPointAtLength method when called with a distance parameter that is out 
of range.  My question is the same as the one asked in the following email 
by Kevin Lindsey:

Could you please provide some clarification on this matter and either post 
the information in an errata to the 1.1 specification or include it in the 
1.2 version.

Thanks!
-Alex
