output.xml schema: Enhance XSD 1.1 compatibility.

pekkaklarck · pekkaklarck · commit 4def26ce981f · 2021-03-08T01:08:41.000+02:00
Add maxOccurs to keyword assignment and arguments. These are needed if xs:choice groups are converted to xs:all groups when using XSD 1.1. That would make the schema more strict. Related to robotframework#3726.
