cfinput Submit Button Not Working on hostexcellence.com

The coldfusion cfinput tag no longer accepts 'SUBMIT' as a valid value for the 'TYPE' attribute. This means cfforms are no longer useable on the server, and all pages that use cfforms will not work. Users of our website cannot log in. I submitted a trouble ticket to hostexcellence.com about this problem and sent them 2 examples of cfm that don't work. They tested their server with a plain html "<input>" tag and claimed the problem is resolved. The following is an example of the cfinput tag that will not work:

<cfform name="form1" method="post" action="">
<label>A label
<cfinput type="text" name="text">
</label>
<label>
<cfinput type="submit" name="Submit" value="Submit">
</label>
</cfform>

This gives the following error on the hostexcellence server:

Error Diagnostic Information
Attribute set validation error in tag CFINPUT

The tag has an invalid attribute combination: the value of the tag switch attribute 'TYPE' which is now 'SUBMIT' is invalid. The valid attribute values are

TEXT
PASSWORD
CHECKBOX
RADIO

Has anyone encountered this problem with the submit button? I went so far as to check sandbox security, and I found no way to restrict the cfinput tag, nor can I think of a reason to restrict use of the submit button in the cfinput. Could someone please get back to me if they've got any idea why this problem occurs?

Thanks in advance
