## Class XSAttributeChecker

- java.lang.Object
- - org.apache.xerces.impl.xs.traversers.XSAttributeChecker

-     public class XSAttributeChecker
      extends java.lang.Object

  Class `XSAttributeCheck` is used to check the validity of attributes appearing in the schema document. It - reports an error for invalid element (invalid namespace, invalid name) - reports an error for invalid attribute (invalid namespace, invalid name) - reports an error for invalid attribute value - return compiled values for attriute values - provide default value for missing optional attributes - provide default value for incorrect attribute values But it's the caller's responsibility to check whether a required attribute is present. Things need revisiting: - Whether to return non-schema attributes/values - Do we need to update NamespaceScope and ErrorReporter when reset()? - Should have the datatype validators return compiled value - use symbol table instead of many hashtables

  - ### Method Detail

    - #### reset

          public void reset(SymbolTable symbolTable)

    - #### checkAttributes

          public java.lang.Object[] checkAttributes(org.w3c.dom.Element element,
                                           boolean isGlobal,
                                           org.apache.xerces.impl.xs.traversers.XSDocumentInfo schemaDoc)

      Check whether the specified element conforms to the attributes restriction an array of attribute values is returned. the caller must call `returnAttrArray` to return that array.
      Parameters:
        `element` - which element to check
        `isGlobal` - whether a child of <schema> or <redefine>
        `schemaDoc` - the document where the element lives in
      Returns:
        an array containing attribute values

    - #### checkAttributes

          public java.lang.Object[] checkAttributes(org.w3c.dom.Element element,
                                           boolean isGlobal,

                                           boolean enumAsQName)

      Check whether the specified element conforms to the attributes restriction an array of attribute values is returned. the caller must call `returnAttrArray` to return that array. This method also takes an extra parameter: if the element is "enumeration", whether to make a copy of the namespace context, so that the value can be resolved as a QName later.
      Parameters:
        `element` - which element to check
        `isGlobal` - whether a child of <schema> or <redefine>
        `schemaDoc` - the document where the element lives in
        `enumAsQName` - whether to tread enumeration value as QName
      Returns:
        an array containing attribute values
