aggregate functions in bind
While the SPARQL 1.1 Query Language recommendation appears to allow
aggregate functions for Bind (
https://www.w3.org/TR/2013/REC-sparql11-query-20130321/#rBind), I have done
some testing and I believe that aggregate functions may not be used in a
bind statment.
e.g there is no valid query where "BIND( min(?x) as ?min )" is valid
Does anyone know of an example where aggregate functions are permissible?

Doh!
Thank you Andy for once again politely showing that RTFM does not mean Skim
the fine manual. ;)
