lemminx Parser gets confused by DTDs

Download https://github.com/AnIML/techniques/raw/master/ecd-trace.atdd
rename it to .xml
Download https://github.com/AnIML/techniques/raw/master/animl_unit_entities.dtd
open the renamed xml inside eclipse
You get a lot of Element type "..." must be declared.
Now remove the line <!DOCTYPE Technique SYSTEM "animl_unit_entities.dtd">
Now the errors are gone (but you will see ones complain about missing entities defined in the DTD of course)

With intellij I have the same problem. I wonder if it's a valid DTD or if we need to set a xerces option to support it.

I can only tell that when parsing the file with JAXB there is no complaint even when validation against the XSD.

The only issue I faced was that java by default do not allow to load DTDs from any source so for development purpose I enabled the following setting -Djavax.xml.accessExternalDTD=all

I have the impression that it's the same issue https://www.oxygenxml.com/forum/post36904.html#p36904

I can parse and validate the files with JAXB no idea if it uses xerces under the hood at all :-)
