You are missing my point. The document

  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd" [
  <!ATTLIST html
      xmlns:xsi CDATA #FIXED "http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation CDATA #IMPLIED

  ]>
  <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.w3.org/1999/xhtml
          http://www.w3.org/2002/08/xhtml/xhtml1-strict.xsd">
    <head><title></title></head><body><p>...</p></body>
  </html>

is either invalid XHTML 1.0 Strict or as valid as

  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
      "http://www.w3.org/2002/08/xhtml/xhtml1-strict.dtd">
  <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.w3.org/1999/xhtml
          http://www.w3.org/2002/08/xhtml/xhtml1-strict.xsd">
    <head><title></title></head><body><p>...</p></body>
  </html>

I'd be fine if the validator ignores the internal subset and thus claims
both documents to be invalid.
