Re: [FO] fn:substring arguments

I saw in the F&O spec, that fn:string-length() function returns value
of type xs:integer.

I think that string-length is semantically equivalent to $startingLoc
(as mentioned in my previous post below). I mean that $startingLoc is
always <= string-length.

Shouldn't it then be appropriate to make $startingLoc as xs:integer
(for the fn:substring function)?
