text/plain content type

Thank you for providing this very valuable service. I validate reams of
documents. Occasionally, one html document that is just like all the others
will not validate. The validator returns the following message: (with a
yellow background)

Sorry, I am unable to validate this document because its content type is
text/plain, which is not currently supported by this service.

I've copied the following two statements from files that DO validate to
those that do NOT, to no avail:

 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

The files are saved w/ an .htm extension.

Can you provide insight into this error? I did not see it listed w/ the
other validation type error messages.

Thanks much!
