[rules-users] Regarding using lessthan(<) and lessthan or equal(<=) operator in rules file

[Mahaan]

Hi All,

I am using lessthan(<) and less than or equal (<=) operator in LHS part of a
XML rule file which is like this.

<eval> obj.getValue < 10 </eval>

but when i am giving it to rule engine for execution, its throwing the
following exception:

(null: 1, 214): cvc-elt.1: Cannot find the declaration of element 'package'.
(null: 1, 569): The content of elements must consist of well-formed
character data or markup.
