http://www.w3.org/Bugs/Public/show_bug.cgi?id=5171 Summary: Confusing and contradicting sections on resolving inter- document references Product: SML Version: unspecified Platform: PC OS/Version: Windows XP Status: NEW Severity: normal Priority: P2 Component: Core+Interchange Format AssignedTo: cmsmcq@w3.org ReportedBy: popescu@ca.ibm.com QAContact: public-sml@w3.org Section 3.4.6-Resolving Inter-document References says that references containing only fragments must point to the document in which they occur. But section 3.4.5- Relative Reference above requires a [base URI] to be specified for any relative reference : If any inter-document reference or any alias of any document in the interchange set is a relative URI, then the [base URI] property as defined by Infoset [XML Information Set] MUST be used to specify a base URI for these references. Issues: 1. A URI fragment is also a relative URI so 3.4.5 must apply to fragments. By doing that is quite possible that the URI resulted by applying the [base URI] to that fragment to be equivalent with a document alias in the IF set. Which means the fragment may point to outside documents Possible resolutions: 1. fragment URIs are not required to have [base URI] defined (update 3.4.5 to say that). They always point to the document containing them. If a [base URI] is defined at instance document level, within the document containing the fragment, and the [base URI] applies to this fragment, there should be no attempt to match the resulted URI with a document alias in IF. If a [base URI] is defined globally, at the IF level, this [base URI] should not be applied to fragments. In other words, resolution 1 says that fragments are always pointing to the same document containing them. 2. Fragments behave just like any other relative URI. The only difference is that they are not required to have a [base URI] specified since they may be just references pointing to the same document. If [base URI] are specified, locally or globally, fragments are required to observe them; as a result fragment identifiers MAY and up pointing to documents other then the one containing them.
