Evaluate moving to xsd 1.1 #331
Description
The XSD 1.1 is presenting a lot of improvements over XSD 1.0 which is used in MMD. Using 1.1 would allow us for example to remove the forced sequence for mandatory fields, and have a better handling of choice and occurrence. Validation tools like xmllint will not work with XSD 1.1, as based on libxml2 supporting only XSD 1.0.
This is not a priority, but we should investigate the possibility to upgrade and its impact on workflows/tools/software we are using related to MMD validation.
