ELMAH 1.0 Beta2 to 1.0 Beta3 upgrade gotcha

In one of my projects, I upgraded ELMAH from 1.0 Beta2 to 1.0 Beta3.  I have 404 filtering turned on so that my log doesn't get flooded with 404 notifications (usually caused by legitimate, albeit a tad overzealous, monitoring applications).  Here is what the Web.config element looks like for Beta2:

<equal binding="HttpStatusCode" value="404" valueType="Int32" />

All of a sudden, when I fired up my site, I started getting a weird error message:

The Empty value type is invalid for a comparison.

It turns out that the XML schema has changed ever so slightly in 1.0 Beta3.  To fix the aforementioned error, you must change the "valueType" attribute to "type", like this:

<equal binding="HttpStatusCode" value="404" type="Int32" />

Hopefully this will save someone some pain.
