<td>The content of the data is represented in the resource narrative.</td>
<td>It may be linked by internal references (e.g. xml:id). This usually implies that the value could not be represented in the correct format - this may be due to system limitations, or this particular data value.</td>

<tr>
<td>2</td>
<td style="white-space:nowrap"> not-a-number
<a name="data-absent-reason-not-a-number"> </a>
</td>
<td>Not a Number (NaN)</td>
<td>The numeric value is undefined or unrepresentable due to a floating point processing error.</td>

<a name="data-absent-reason-not-permitted"> </a>

<td>Not Permitted</td>

<td>This is most often associated with required bindings that do not include the actual code used, but may be used with other data types.</td>
