Data-model, item-at accessor, why the index typed as xs:decimal?

Hello!

Excuse me if I missed something, just one question. In XQuery1.0 
XPath2.0 Data model defined item-at accessor, which "returns the item in 
the sequence at the specified index" and this index is defined as 
xs:decimal. Is there a reason for the index to be decimal rather than 
integer? If so, anyway, the rules of rounding must be defined also.
