That is right, thanks, i found the full Note (October 03, 1998):

"Author's Note: It is somewhat remarkable to think that this article,
which appeared initially in the Winter 1997 edition of the World Wide Web
Journal was out of date by the time the final XML Recommendation was
approved in February. And even as this update brings the article back into
line with the final spec, a new series of recommendations are under
development. When finished, these will bring namespaces, linking, schemas,
stylesheets, and more to the table.

This introduction to XML presents the Extensible Markup Language at a
reasonably technical level for anyone interested in learning more about
structured documents. In addition to covering the XML 1.0 Specification,
this article outlines related XML specifications, which are evolving. The
article is organized in four main sections plus an appendix."

That is right, thanks. It is a PI when considered SGML but not a PI when
considered the XML subset.
