For now, I think that "local locale" is the best single choice because if
the user wants the XSD standard form "1.23" they can workaround it with a call
`str()` and print a string. Not perfect but gives them a way.
XSD F&O v3.1 has "picture strings" :
https://www.w3.org/TR/xpath-functions-3/#dt-picture-string : that looks like
Java DecimalFormat, not printf style.
I think most people are familiar with printf and things like padding
strings and alignment are covered. We can refine the capabilities after the
machinery is in.

> Key: JENA-967
> URL: https://issues.apache.org/jira/browse/JENA-967
> Project: Apache Jena
> Issue Type: New Feature
> Components: ARQ
> Reporter: Stuart Williams
> Priority: Minor
>
> There are situations where it would be useful to be able to format strings
> bound to variable. In particular I have wanted to create some zero-filled
> numeric strings.
> I've accomplished the task with a pair of BINDs as follows where {{?code}} is
> bound to a numeric string:
> {noformat}
> BIND( "000000" as ?zfill )
> BIND(
> concat(if(strlen(?code)>=strlen(?zfill),"",substr(?zfill,strlen(?code)+1)),?code)
> as ?reg_notation)
> {noformat}
> But it would have been nice to be able to use something less opaque like:
> {noformat}
> BIND( afn:printf("%06d",?code) as ?reg_notation)
> {noformat}
> So 'improvement'/'new feature' suggestion is an additional ARQ Extension
> function that exposes java {{printf}} method.
