Be able to hook up custom moddle extension

[nikku]

For improved validation of extended BPMN models it would be beneficial to be able to register a custom moddle extension so that we can do the following, i.e. as part of rules:

function check(node, reporter) {
  if (is(node, 'camunda:Callable')) {
    // custom check, 1212
  }
}

Any update on this? This would be some nice functionality that we could use. Right now some of our nodes have some extended properties that won't show up.

Happy to take a contribution to add this behavior.

I would also like to see this. It appears that all that is needed is to pass the extensions schema to the BpmnModdle constructor here: https://github.com/bpmn-io/bpmnlint/blob/77b77bd0087af2a610ece67d8a2d4303b3d8c76a/bin/bpmnlint.js#L56
