So, this is a issue on how the EPG is handle, isn't it? Is so, I think is not a possible solution for that
I don't understand your question ... where do you see the issue in the ETSI EN 300 468 standard or in the “piece” of XML file you provided? If it's standard, you're not exactly in the right place.... If it is in the XML strings you provided, then fix them as required by the standard.
