Unknown element 'html' error when there is no such element

[Optimum]

I'm attempting to test the plum dev system for inbound calls. I'm getting the following error in the error log:

DocumentParser::FetchDocument - Parse error in file "http://dev.oc-meridian.com/OCQDev/servi ... uWB5a2twkA.", line 1, column 6 - Unknown element 'html'
errno: 205 uri http://dev.oc-meridian.com/OCQDev/servi ... uWB5a2twkA.

Entering that URL in a browser, I get a properly formatted VXML document with no "html" element. The document also parses when I parse the document via the URL from within my PlumDev account.

An explanation of what is going wrong here would be much appreciated.

Hi,

Are you still encountering any issues with this?

When we plug your application URL, http://dev.oc-meridian.com/OCQDev/servi ... uWB5a2twkA, to a phone number and dial into it, we encounter no errors.
