First of all, the quoted claim was not that the DOM did not conform to
the Infoset because it reported CDATA sections, but that it did not
conform because it didn't have a simple way to convert all CDATA nodes
to text nodes.
But it was mistaken even in that respect: the Infoset imposes no
constraints on what a standard may specify, only on how it specifies
it. It defines vocabulary for standards to use. In the case of CDATA
sections, it doesn't define any vocabulary so a spec that wants to
refer to CDATA sections has to use its own terminology. The DOM will
just do that (as it does now).
Here is the full text of the conformance section of the current
infoset draft, in the hope of preventing further misunderstanding:
Since the purpose of the Information Set is to provide a set of
definitions, conformance is a property of specifications that use
those definitions, rather than of implementations.
Specifications referring to the Infoset must:
Indicate the information items and properties that are needed to
implement the specification. (This indirectly imposes conformance
requirements on processors used to implement the specification.)
Specify how other information items and properties are treated (for
example, they might be passed through unchanged).
Note any information required from an XML document that is not
defined by the Infoset.
Note any difference in the use of terms defined by the Infoset (this
should be avoided).
If a specification allows the construction of an infoset that has
inconsistencies as described above under Synthetic Infosets it may
describe how those inconsistencies are to be resolved, and should do
so if it provides for serialization of the infoset.
