[jira] [Commented] (MNG-5986) XML validators flag errors on poms
that declare plugin configurations using the 'combine.self' attribute
because the maven-4.0.0 XSD does not declare this attribute.

What rules do we have for changing the schema outside of a major release?

> Key: MNG-5986
> URL: https://issues.apache.org/jira/browse/MNG-5986
> Project: Maven
> Issue Type: Bug
> Components: POM
> Affects Versions: 3.3.3
> Environment: All
> Reporter: Ben Tels
> Priority: Minor

> Maven recognizes an attribute 'combine.self' on the 'configuration' element within plugin declarations within a POM ('configuration' elements within and outside 'execution' elements). However, an XML validator flags use of this attribute as an error. Which is correct, because published XSD http://maven.apache.org/xsd/maven-4.0.0.xsd does not declare 'combine.self' as an attribute of 'configuration'.
> Current declaration of the configuration element:
> <xs:element name="configuration" minOccurs="0">
> <xs:annotation>
> <xs:documentation source="version">4.0.0</xs:documentation>
> <xs:documentation source="description">The configuration of the reporting plugin.</xs:documentation>
> </xs:annotation>
> <xs:complexType>
> <xs:sequence>
> <xs:any minOccurs="0" maxOccurs="unbounded" processContents="skip"/>
> </xs:sequence>
> </xs:complexType>
> </xs:element>
> Simple fix:
> <xs:element name="configuration" minOccurs="0">
> <xs:annotation>
> <xs:documentation source="version">0.0.0+</xs:documentation>
> </xs:annotation>
> <xs:complexType>
> <xs:sequence>
> <xs:any minOccurs="0" maxOccurs="unbounded" processContents="skip"/>
> </xs:sequence>
> <xs:attribute name="combine.self" type="xs:string" use="optional"/>
> </xs:complexType>
> </xs:element>
