           Summary: R-174: Question re: PSVI document property
           Product: XML Schema
           Version: 1.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSD Part 1: Structures
        AssignedTo: ht@w3.org

The definition for {namespace schema information information items} [1] 
includes 3 properties - {schema namespace}, {schema components}, {schema 
documents}. 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.
