CX_SXML_ERROR is not released on Steampunk

[larshp]

see https://abapedia.org/steampunk-2302-api/

any opinion on how to avoid using it?

I probably recommend replacing it with all the CLAS CX_SXML_ILLEGAL_ARGUMENT_ERROR CLAS CX_SXML_INTERNAL_ERROR CLAS CX_SXML_NAME_ERROR CLAS CX_SXML_PARSE_ERROR CLAS CX_SXML_STATE_ERROR

instead

I wouldn't narrow it to a specific list. The idea was the opposite. I'd better replace with cx_dynamic_check instead. It is just in one place, if I remember well ? And very close (thus limited) to parsing
