  // Performs various validation steps on the descendants of

  // 'selector'. Elements that should be validated must have an

  // attribute named "data-validate" which is set to a space-separated

  // list of tests to perform. Additionally, the attribute

  // "data-title" must be set to a human-readable name of the field

  // that can be shown as part of an error message.

  //

  // Supported validation tests are:

  // - "required": the field must be set (its .val() must not be empty)

  //

  // The validation will abort and return "false" as soon as

  // validation routine fails.

  //

  // The function returns "true" if all validations succeed for all

  // elements.
