Notable Changes

Useimmutable.Seq: for Scala 3 and 2.13, the result type ofNode.child /Node.nonEmptyChildren /Node.attribute is changed fromcollection.Seq toimmutable.Seq (#760)

• Scala 2.13 changed the defaultscala.Seq alias toimmutable.Seq, but the scala-xml library continued to usecollection.Seq. This often results in.toSeq conversions when using scala-xml in Scala 3 or 2.13.
• scala-xmlwas always immutable in spirit,NodeSeq extendsimmutable.Seq
• A relatedchange to the Scala compiler is under review to encode XML literals asVector[Node]
