Hi Assaf!
According to the BPEL Spec (1.1) for bpws:getVariableData
('variableName', 'partName'?, 'locationPath'?):
"If the given locationPath selects a node set of a size other than one
during execution, then the standard fault bpws:selectionFailure MUST be
thrown by a compliant implementation."
Since yyy does not exist wouldn't it cause an exception?
This seems to contradict your assertion that it should evaluate to
false.

Doug,
An XPath expression can be asked to return a node set, boolean, integer
or
string. In this case, the XPath expression is expected to return a
boolean
value. For an expression like this, the value is true if there's one or
more
nodes, zero if no node can be selected.
