Hi Andy,

I think section 11.6 Extensible Value Testing of the RC is buggy:
The function aGeo:distance is declared as:
  xsd:boolean   aGeo:distance (numeric x, numeric y)

But used as
  xsd:nonNegativeInteger aGeo:distance(numeric x1, numeric y1, numeric
x2, numeric y2)

in the second example
  FILTER ( aGeo:distance(?axLoc, ?ayLoc, ?bxLoc, ?byLoc) < 10 ) .

Or am I missing something very obvious?

PS: It's even unclear how a the property aGeo:location could mean X and
Y part of the location at the same time? I think it's perfectly possible
to get a solution for ?axLoc which is in fact a Y because it's the same
property.. just another ordering

Best regards,
   Thomas
