Hello all,

I have some more comments on the new cd-1 functions string-substring and
uri-substring:

1.  The standard should define what happens if  the second or third
parameter of this function is out of bounds of the string/uri.

2. The standard should define for the uri-substring function what
happens if the resulting substring is not a valid uri
(e.g. substring(urn:oasis:names:tc:xacml, 4,10) == 'oasis:' )

Regards,

Ludwig

All,

I propose that in all cases the result of the function shall be 
Indeterminate with a status code of "processing-error".

Best regards,
Erik
