> The issue can be seen when running an xpath query for nodes that have a boolean property set to false:
> bq. //*[(child/@prop = 'false' or not(child/@prop))]
> this translates into 
> bq. select [jcr:path], [jcr:score], * from [nt:base] as a where [child/prop] = false or [child/prop] is null
> the second _or_ part is wrong and selects more than it should: 'or [child/prop] is null'
