The system identifier must begin with either a single or double quote character

I've an XML schema that references the a well-known schema hosted on the web.

http://www.w3.org/XML/1998/namespace.xsd

Via:

<xs:import namespace="http://www.w3.org/XML/1998/namespace" schemaLocation="http://www.w3.org/XML/1998/namespace.xsd"/>

Via dependencies I haven't chased down, it references this:

http://www.w3.org/XML/2000/xmlschema/versionInfo.ent

Which has a validation error according to Xerces, saying:

The system identifier must begin with either a single or double quote character.

This was causing my entire schema chain to fail validation. I've removed the xs:import from any my schemas and now its fine, but is there a problem with this .ent file?

It seems a common error in Google and I wonder if other systems are hitting it.

If you display that document in your browser it includes the following near the start:

<documentation>
!!!THIS SCHEMA DOCUMENT IS OUT OF DATE!!! It uses a preliminary W3C XML Schema
syntax which has been superseded. The up-to-date version is at
http://www.w3.org/2001/xml.xsd
