[dmarc-ietf] RUA XML : maxOccurs="unbounded" not allowed

[OLIVIER HUREAU <[e-mail]>]

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. 
``` 
[ https://www.w3.org/TR/xmlschema-1/#cos-all-limited | https://www.w3.org/TR/xmlschema-1/#cos-all-limited ] [ https://www.w3.org/TR/xmlschema-1/#cos-all-limited ] 

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