The XML Schema Recommendation specifies that the {schema components} property could be empty: [[ The {schema components} property is provided for processors which wish to provide a single access point to the components of the schema which was used during assessment. Lightweight processors are free to leave it empty.. ]] On the other hand, the specification seems to require that the {documents} property should be exposed by all (including lightweight) processors. Since exposing schema documents is as expensive as exposing schema components, this requirement seems unreasonable, and thus looks like a bug in the spec.

RESOLVED: class R-174 as issue for 1.1 (RQ-144) ACTION: MSM to write Elena Litani explaining our decision on this candidate erratum and noting that since every property in the infoset is optional, the provision of a document information item can be approximately as lightweight as the implementor cares to make it. (In particular, it can be just the [base URI] property, or in the extreme case an 'information item' with no properties at all.)
