I'll bet we could use the expression syntax to get properties and then
invoke ThrowModelError if things aren't right.
See also $PTII/ptolemy/kernel/attributes/RequireVersion.java for
how we require a specific version of Java.
Perhaps this could be extended to have a parameter that takes an expression
that must evaluate to true.  We might use something like
getProperty("java.whatever")== "Windoze" || findFile("MyBinary")
(The syntax is probably off)
