RE: DOCBOOK-APPS: Question about the ENTITY references

[David Cramer <dcramer at broadjump dot com>]

Not. This is one of XMetaL's many limitations. Attached is a test case I provided XMetaL support long ago. Out of curiosity, what version of XMetaL are you using? I was working with 2.1 when I reported the problem. They're response was basically "don't do that."

• Subject: Another problem with XMetaL

In the attached test case, XMetaL fails to find the file "sharedResource.xml" ('Can't find file "../sharedResources/sharedResource.xml" for external entity "sharedResource"'). It appears that XMetaL is looking for sharedResource.xml relative to the file testOfEntityResolution.xml rather than relative to parameter.ent. This in contradiction to the xml spec and common sense. It just doesn't make sense to look for the resource relative to where the entity is referenced, since it could be referenced in any number of different resources, each of which would require a different relative uri.

According to the XML spec: "Unless otherwise provided by information outside the scope of this
specification..., relative URIs are relative to the location of the resource within which the entity declaration occurs." (See link and paragraph below).

The entity sharedResource is declared in the file parameter.ent so it should be found relative to parameter.ent. Is there a way to make XMetaL conform to the xml spec?

"[Definition: The SystemLiteral is called the entity's systemidentifier. It is a URI reference (as defined in [IETF RFC 2396], updated by [IETF RFC 2732]), meant to be dereferenced to obtain input for the XML processor to construct the entity's replacement text.] It is an error for a fragment identifier (beginning with a # character) to be part of a system identifier.  Unless otherwise provided by information outside the scope of this specification (e.g. a special XML element type defined by a particular DTD, or a processing instruction defined by a particular application specification), relative URIs are relative to the location of the resource within which the entity declaration occurs. A URI might thus be relative to the document entity, to the entity containing the external DTD subset, or to some other external parameter entity.]"
