Hi,
I have tried to run some measurements with the new XSD but it seems that it is
not valid :
```
xmlschema.validators.exceptions.XMLSchemaParseError: attribute
maxOccurs='unbounded': value must be one of [0, 1]:
```
The complex type "ReportMetadataType" has a <xs:all> (see below).
However the Python library i am using refuses the XSD files as, according to
W3, macOccurs unbounded are not accepted in all :
```
Schema Component Constraint: All Group Limited
When a model group has {compositor} all, then all of the following must be
true:
1 It appears only as the value of one or both of the following properties:
1.1 the {model group} property of a model group definition.
1.2 the {term} property of a particle with {max occurs}=1which is part of a
pair which constitutes the {content type} of a complex type definition.
2 The {max occurs} of all the particles in the {particles} of the group must be
0 or 1.
```

Shouldn't we remove the maxOccurs for the error element ?
