Property Annotations

Property annotations describe the class of annotations which are stored as a property on an object
example: : Property annotations may appear on paragraph properties, run properties, table rows, etc.
In these cases, the annotation's semantics are defined by the property, as they can affect content and/or formatting.
example:
<w:p>
  <w:r>
    <w:rPr>
      <w:b/>
      <w:rPrChange  >
        <w:rPr/>
      </w:rPrChange>
    </w:rPr>
    <w:t>Example</w:t>
  </w:r>
  <w:r>
    <w:t xml:space="preserve"> text.</w:t>
  </w:r>
</w:p>

The <rPrChange> element (§2.13.5.32; §2.13.5.33) contains the set of previously applied revision properties associated with a particular author at a particular time. It is stored itself as a property on the parent run which was modified. ]
