Dear Makoto,

thank you very much. I don't think this the same issue. The problem with DR
16-006 is how to handle what are essentially denormalised relations such as
between CellStyle and CellStyleXfs such as the following:

<cellStyles >
  <cellStyle name="20% - Accent1" xfId="3" builtinId="30"/>
  <cellStyle name="Heading 1" xfId="2" builtinId="16"/>
  <cellStyle name="Normal" xfId="0" builtinId="0"/>
  <cellStyle name="Title" xfId="1" builtinId="15"/>
</cellStyles>

<cellStyleXfs>
  <xf numFmtId="0" fontId="0" fillId="0" borderId="0"/>
  <xf numFmtId="0" fontId="2" fillId="0" borderId="0" applyNumberFormat="0"
applyFill="0" applyBorder="0" applyAlignment="0" applyProtection="0"/>
</cellStyleXfs>

As things stand I thing this would be valid XML but likely to cause
problems for applications.

There should be a constraint such that len(//cellsStyle/*) =
len(//cellStyleXfs/*) I'm not so hot on XSL but maybe there should be
relevant ref attributes in the schema?

<xsd:complexType name="CT_CellStyle" ref="xf">
  <xsd:sequence>
     <xsd:element name="extLst" type="CT_ExtensionList" minOccurs="0"
maxOccurs="1"/>
  </xsd:sequence>
  <xsd:attribute name="name" type="s:ST_Xstring" use="optional"/>
  <xsd:attribute name="xfId" type="ST_CellStyleXfId" use="required"/>
  <xsd:attribute name="builtinId" type="xsd:unsignedInt" use="optional"/>
  <xsd:attribute name="iLevel" type="xsd:unsignedInt" use="optional"/>
  <xsd:attribute name="hidden" type="xsd:boolean" use="optional"/>
  <xsd:attribute name="customBuiltin" type="xsd:boolean" use="optional"/>
</xsd:complexType>

Unfortunately, a constraint the other way is not possible because the xf
type is used in different contexts with different elements (I've submitted
a DR in the past along these lines): a base type would help here.
