Generally, just write the method in the Java code and reference it
from the tml, i.e.:

.tml:

  You have at least ${min(1, remainingMinutes)} minutes before detonation]

.java

public int min(int op1, op2) { return Math.min(op1, op2); }


... though in practice, you might have more of the string generated in
Java code so that you can say "minute" vs. "minutes" dependency on the
cardinality.  In any case, the static method access in OGNL was useful
in T4 where templates were reloadable but classes were not. In T5 its
better to keep the templates simple by moving non-trivial logic to the
Java code.
