The example schema [ComplexTypeAttributeGroupExtension.xsd] has been classified as being an Advanced XML Schema Patterns for Databinding 1.0 conformant document as it only exhibits the following patterns:

Status Nodes Name XPath
basic TargetNamespace .[@targetNamespace]/ (., @targetNamespace)
basic QualifiedLocalElements .[@elementFormDefault = 'qualified']/ (@elementFormDefault)
basic UnqualifiedLocalAttributes .[not(@attributeFormDefault) or @attributeFormDefault = 'unqualified']/ (., @attributeFormDefault)
basic IdentifierName .//.[matches(@name, "^[A-Za-z_]([A-Za-z0-9_]0 31)$")]/ (@name)
basic NonIdentifierName .//.[@name and not(matches(@name, "^[A-Za-z_]([A-Za-z0-9_]0 31)$"))]/ (@name)
basic GlobalElement ./xs:element[@name and @type and contains(@type, ':')]/ (., @name, @type)
basic AttributeFormUnqualified .//xs:attribute[@form='unqualified']/ (@form)
basic AttributeOptional .//xs:attribute[@use = 'optional']/ (@use)
basic GlobalComplexType ./xs:complexType[@name]/ (., @name)
basic ComplexTypeSequence .//xs:complexType/xs:sequence/ (., xs:element/(., @name))
basic GlobalElementSequence ./xs:element[@name]/xs:complexType/xs:sequence[xs:element]/ (../../(., @name), .., ., xs:element/(., @name))
