[Open-scap] variable number of instance problem

[Karim BENZINA]

Hi,
I'm trying to insert a variable as number of instance in 30001 object. I
need to check that the number of instance is equal to a local variable that
i provide but it does not work.
Could you help me to use a variable as a number of occurence of my pattern
match.

In my example, if i put 4 as below , it works (result is true)
<ind:instance datatype="int" operation="equals">4</ind:instance>

but it put the variable which has a value of 4, it does not work(result is
false).
<ind:instance datatype="int"
operation="equals">oval:x:obj:30002</ind:instance>

Thank you in advance for your help.

Please find below my oval script.
