    Description

      Observed in MDSAL-423, when a leafref contains a function invocation:

      leaf flavor {
  type leafref {
    path "deref(../../../ext-cpd/int-virtual-link-desc)/../desc-flavor/id";
  }
}

      we end up splitting the path, but not account for the call correctly, leading to:

      java.lang.IllegalArgumentException: Parameter 'localName':'int-virtual-link-desc)' contains illegal character ')'
