SPARQL 1.1 support in 4store?

I am using BIND ( ) to select and Insert triples, from and to 4store.

The following SELECT works,

PREFIX Sensor: <http://cei.usc.edu/Equipment.owl#>
SELECT * 
WHERE {
    ?subject100 Sensor:test1 "100"
    BIND("1000" as ?x) .
} LIMIT 10

But when I try to do a INSERT WHERE, it fails

PREFIX Sensor: <http://cei.usc.edu/Equipment.owl#> 
INSERT {  
    ?subject Sensor:test510 ?value  . 
    }  
WHERE { 
    { 
    ?subject100 Sensor:test1 "100" . 
    BIND("200" as ?value)  
    } 
UNION
    { 
    ?subject99 Sensor:test1 "99" . 
    BIND("300" as ?value)  
    } 
    }

error: BIND cannot be used with SPARQL 1.0 at line 1 of operation 0

I am running Latest 4Store v1.1.4 20-Sep-2011

I tried the above INSERT WHERE with a different SPARQL Store and it worked. BIND is a new construct in SPARQL 1.1 so I am not sure if it is supported in 4Store.

BIND is not supported in 4store 1.1.4. It will probably be supported in the next version. There has been some discussion about this already.
