Sorry, those APIs are not in place yet. I have JIRA issue add
optional validators, which is a loose, general term for what you are
aiming for ("password is required if userName is given").
I think some relationships may not be expressable using the @Validate
annotation, i.e., the string representation; I'm thinking there will
be a kind of JavaScript template object that will be used to generate
some kinds of JavaScript.
Things have slowed down on 5.0 for a moment, while I work on an urgent
client project (in Tapestry 5).
