The example schema [NillableOptionalElement.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 GlobalElement ./xs:element[@name and @type and contains(@type, ':')]/ (., @name, @type)
basic ElementMinOccurs0 .//xs:element[@minOccurs = '0' and (not(@maxOccurs) or @maxOccurs = '1')]/ (@minOccurs, @maxOccurs)
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))
basic SequenceElement .//xs:sequence/xs:element/(.)
advanced NillableOptionalElement .//xs:element[@nillable = 'true' and @minOccurs = '0']/ (@nillable, @minOccurs)
basic ElementTypeReference .//xs:element[@name and @type and namespace-uri-from-QName(resolve-QName(@type,.)) != 'http://www.w3.org/2001/XMLSchema' and contains(@type, ':')]/ (., @name, @type)
basic ElementReference .//xs:element[@ref and contains(@ref, ':')]/ (., @ref)
basic StringElement .//xs:element/@type[resolve-QName(.,..) = xs:QName('xs:string')]
basic GlobalElementComplexType .//xs:element[parent::xs:schema]/xs:complexType / (.,..)

To facilitate testing, the example schema element has been wrapped in the following descriptions:
