    Methods
    Modifier and Type | Method and Description
    --- | ---
    `static boolean` | `checkComplexDerivationOk(XSComplexTypeDecl derived, org.apache.xerces.xs.XSTypeDefinition base, short block)` check whether complex type derived is valid derived from base, given a subset of {restriction, extension}.
    `static void` | `checkElementDeclsConsistent(XSComplexTypeDecl type, XSParticleDecl particle, SymbolHash elemDeclHash, SubstitutionGroupHandler sgHandler)`
    `static boolean` | `checkSimpleDerivationOk(XSSimpleType derived, org.apache.xerces.xs.XSTypeDefinition base, short block)` check whether simple type derived is valid derived from base, given a subset of {restriction, extension}.
    `static boolean` | `checkTypeDerivationOk(org.apache.xerces.xs.XSTypeDefinition derived, org.apache.xerces.xs.XSTypeDefinition base, short block)` check whether derived is valid derived from base, given a subset of {restriction, extension}.B
    `static java.lang.Object` | `ElementDefaultValidImmediate(org.apache.xerces.xs.XSTypeDefinition type, java.lang.String value, ValidationContext context, ValidatedInfo vinfo)` check whether a value is a valid default for some type returns the compiled form of the value The parameter value could be either a String or a ValidatedInfo object
    `static void` | `findElemInTable(XSComplexTypeDecl type, XSElementDecl elem, SymbolHash elemDeclHash)`
    `static void` | `fullSchemaChecking(XSGrammarBucket grammarBucket, SubstitutionGroupHandler SGHandler, CMBuilder cmBuilder, XMLErrorReporter errorReporter)` used to check the 3 constraints against each complex type (should be each model group): Unique Particle Attribution, Particle Derivation (Restriction), Element Declrations Consistent.
