I'm trying to sort the following based off of @SortOrder

<Result Code="1111111" SortOrder="1">
<Result Code="2222222" SortOrder="2">
<Result Code="3333333" SortOrder="3">
<Result Code="4444444" SortOrder="4">
<Result Code="5555555" >

The problem is, <xsl:sort data-type="number" select="@SortOrder"/> provides the following output:

5555555
1111111
2222222
3333333
4444444

Is there a way to Sort so that if the attribute doesn't exist, that value is pushed to the bottom? I know its possible if the last result looked like <Result Code="5555555" SortOrder="">, but I have no control over input data.

Use @SortOrder as the second sort key, and count(@SortOrder) as the first, with order=descending.
