Observing a schematron issue with scte35 event occuring only with DVB 2018 xsd

[kjerbi]

When using the attached mpd, an issue of schematron validation is raised and I could locate that it happens on the scte35 'signal' and 'binary' excactly when adding this block:
scte35:Signal
scte35:Binary/DAlAABeX1L/AP/wFAUEoUsAf+/+p9opAf4ADbugCpkBCQAAvrGc7g==</scte35:Binary>
</scte35:Signal>
More interesting is that the schematron issue is raised only on DVB 2018 xsd

Would be amazing to know if this is just a small bug or is it due to the fact that scte35:Signal and scte35:Binary are not allowed in DVB 2018.
Many thanks in advance!
