XPath expression test possibilities in Fault Policy file

Question

Hi All,
It would be a great help if someone can show me a way to implement the next case:
I have the next scenario, in a fault policies file I have different actions to execute for the same fault andI have to choose what action will be executed checking a value that has not relation with the $fault variable. The value indicates the number of retries that I have to try the invocation. This is the code, but this code is not working. Anybody knows how to declare the variable to be accesible in the fault policy?
Thanks in advance,
<Conditions>
<faultName xmlns:bpelx="http://schemas.oracle.com/bpel/extension" name="bpelx:remoteFault">
<condition>
<test>$Var=1</test>
<action ref="ora-retry-one"/>
</condition>
<condition>
<test>$Var=2</test>
<action ref="ora-retry-two"/>
</condition>
<condition>
<test>$Var=3</test>
<action ref="ora-retry-three"/>
</condition>
</faultName>
<Conditions>
<Actions>
<Action id="ora-retry-one">
<retry>
<retryCount>5</retryCount>
<retryInterval>2</retryInterval>
<exponentialBackoff>1</exponentialBackoff>
</retry>
</Action>
<Action id="ora-retry-two">
<retry>
<retryCount>7</retryCount>
<retryInterval>2</retryInterval>
<exponentialBackoff>1</exponentialBackoff>
</retry>
</Action>
<Action id="ora-retry-three">
<retry>
<retryCount>9</retryCount>
<retryInterval>2</retryInterval>
<exponentialBackoff>1</exponentialBackoff>
</retry>
</Action>
</Actions>
</faultPolicy>
</faultPolicies>

Hi,
Here is an example of the possible solution:
In fault policy file:
<Conditions>
<faultName xmlns:bpelx="http://schemas.oracle.com/bpel/extension"
name="bpelx:remoteFault">
<condition>
<test>"my_xpath:getRetryCount()=number(1)"</test> (getRetryCount is a custom XPath that returns the number of retries)
<action ref="ora-retry_1"/>
</condition>
<condition>
<test>"my_xpath:getRetryCount()=number(2)"</test>
<action ref="ora-retry_2"/>
</condition>
<condition>
<test>"my_xpath:getRetryCount()=number(3)"</test>
<action ref="ora-retry_3"/>
</condition>
<Actions>
<Action id="ora-retry_1">
<retry>
<retryCount>1</retryCount>
<retryInterval>1</retryInterval>
<exponentialBackoff>1</exponentialBackoff>
</retry>
</Action>
<Action id="ora-retry_2">
<retry>
<retryCount>2</retryCount>
<retryInterval>1</retryInterval>
<exponentialBackoff>1</exponentialBackoff>
</retry>
</Action>
<Action id="ora-retry_3">
<retry>
<retryCount>3</retryCount>
<retryInterval>1</retryInterval>
<exponentialBackoff>1</exponentialBackoff>
</retry>
</Action>
The problem of this solution is that the number of retries is finite but I don't know other way to do it.
Cheers
