handle-marcxml pushes trough broken records without namespace

[TobiasNx]

When an incoming marcxml record without namespace streams through handle-marcxml and this is encoded with encode-xml broken data without record or collection tags are created.

See: https://github.com/TobiasNx/notWorkingFlux/tree/main/marcxmlToMarcxmlWithoutHeader

This does not happen if the handler has the following option handle-marcxml(ignoreNamespace="true")

When encoding to other serialization the behaviour is different:

• encode-json results in empry output
• encode-xml results in exception
