-----------------------------------------

Issue is modifying the value in the infoset which changes its length when length is used by an expression subsequently.

> Bug: should not overwrite the value with truncated value. the fn:string-length function should always return the same value which is the un-truncated length.
> We'll need a separate slot for the truncated value which is generally unused, but when actually outputting data is checked and preferred to the un-truncated value.
