At its meeting of 28 June [1], the XML Schema WG asked me
to transmit the appended comments on the XML Infoset
specification to the XML Core WG.  My apologies for the
delay.

XML Schema CR Review of XML Infoset spec

The purpose of the XML Infoset specification, according to the spec
itself (http://www.w3.org/TR/2001/CR-xml-infoset-20010514/), is:

     ... to provide a consistent set of definitions for use in other
     specifications that need to refer to the information in a
     well-formed XML document [XML].

As a user of the XML Infoset specification, the XML Schema WG has
found that the definitions of information items and their properties
given in the Infoset spec are useful in defining the information which
must be present in the input of an XML Schema processor.  In this
respect, the XML Schema specification may be regarded as a successful
application of the Infoset spec.

We have found, moreover, that the fundamental abstraction of the
information set (i.e. the idea of defining a collection of information
items and their properties) is useful not only in defining the input,
but also in defining the output, of XML Schema processors.  This
abstraction allows us to be precise and specific without requiring a
particular API of XML Schema processors.  In this respect, the
experience of the XML Schema WG may be taken as confirming the basic
utility of the information set as an abstraction over APIs.

Our congratulations to the Core WG on the progress of their work.
