looks like the docs are outdated and the way to call the algorithm is
now different
ALGORITHM: Select by location
INPUT <ParameterVector>
INTERSECT <ParameterVector>
PREDICATE <ParameterGeometryPredicate>
PRECISION <ParameterNumber>
METHOD <ParameterSelection>
OUTPUT <OutputVector>
The PRECISION parameter is not documented in the help file.
Hope this helps
