Re: Jim Melton: XML Query WG review of RIF Datatypes and Built-Ins 1.0

Chris,

Many thanks for the confirmation.  I am, indeed, satisfied (although 
it might be helpful if the text of the spec came right out and said 
this so other readers with the same mental challenges that I have 
won't be similarly confused ;^)

Thanks again!
    Jim
