I understand. You can't do that out-of-the-box, but you can get a hold
of the BitSet (using m.getValue(-1)) and then using ISOUtil.bitSet2byte
in order to get a byte[]. 

Then you can either compare at the byte[] array level or use
ISOUtil.hexString and deal with Strings.

In some of my systems I use a 'CheckField' transaction participant that
you can configure like this:

<participant class="org.jpos.jcard.CheckFields" logger="Q2" realm="CheckRequiredFields">
<property name="mandatory" value="PCODE,7,11,12,13,AMOUNT,PAN,41" />
<property name="optional" value="17,32,37,42,43,46,60,63,111" />
</participant>

you can use the code as a reference: http://jpos.org/private/CheckFields.java
