Description

When I validate the following schema file I get an internal error message.

You can reproduce the issue on the xml-schema-1.1-dev branch, using the jaxp.SourceValidator as follows:
jaxp.SourceValidator -xsd11 -a schema.xsd

---------- schema.xsd file -------------------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:complexType name="baseCt">
<xs:all minOccurs="1">
<xs:element name="elem1"/>
<xs:element name="elem2"/>
</xs:all>
</xs:complexType>

<xs:complexType name="derivedCT">
<xs:complexContent>
<xs:extension base="baseCt">
<xs:all minOccurs="0">
<xs:element name="elem3"/>
<xs:element name="elem4"/>
</xs:all>
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:schema>
------------------------------------------------------

The error message is:

An internal error occurred while formatting the following message:
cos-particle-extends.3.1: When both a derived type and its base have particles with <all> as their

{term}

s, the minOccurs of the derived particle needs to be equal to that of its base.
