17.16.30 sizeAuto

This element specifies that the parent checkbox form field shall be formatted using the point size which is applied to its field characters via the style hierarchy.

[Example: Consider the following WordprocessingML fragment for the properties of a checkbox form field:

<w:r>
  <w:rPr>
    <w:sz w:val="40"/>
  </w:rPr>
  <w:fldChar w:fldCharType="begin">
    <w:ffData>
      <w:checkBox>
        <w:sizeAuto />
        <w:checked w:val="true" />
      </w:checkBox>
    </w:ffData>
  </w:fldChar>
</w:r>

The sizeAuto element specifies that the checkbox must be displayed in the point size of the formatting which would normally be applied to this text via the style hierarchy. In this case, this size is the twenty points specified via the direct formatting on the parent run. end example]
