[Discuss-gnuradio] XML parameter checking

[Mike Rex]

What would be the best way to make sure the user enters a parameter that 
is a multiple of 8 in the GRC XML file?  My first thought is this might 
do the trick, but seems there is no mod function for XML.  Any suggestions?

<check>$psize % 8 = 0</check> or <check>$psize mod 8 = 0</check>
Thanks in advance,
Mike
