Ian, Anne,

you both commented on SVG using an extended form of the functionality  
specified in XML events rather than simply implementing the specification.

The issue turns on the fact that XML Events only allows targets etc within  
a single document, as specified by an IDREF, while the SVG group had hoped  
to allow richer application development by allowing the attributes to  
specify an IRI, without requiring implementation of two redundant (because  
of small but important incompatibilities) version of XML event markup.

The principle behind this is clearly laid out in the Architecture of the  
World Wide Web [1]. Following discussion with the XML Events  
specification's creators and others, the conclusion was that the approach  
taken maximised compatibility with both the current specification, the  
principles of the Architecture of the WWW, and what we could reasonably  
expect to see in the future.

Since, in practice, the group planned to limit the current scope of event  
description to within a document to simplify implmentation for SVG 1.2  
tiny, and since there is no barrier to implementing a future enhanced  
version of XML events in SVG-capable user agents, the group has decided to  
compromise the goal of taking best advantage of the Web now in order to  
simplify compatibility with the existing XML events specification, and  
will therefore use the existing XML events specification as it is. We  
believe this is exactly what you have requested in your comments.

In order to provide the ability to use the Web at large, we will therefore  
rely on people having to implement a successor XML Events specification as  
well, if or when that becomes available.

We hope that this response satisfies you - if not, please let us know  
within two weeks. Thanks!!!

SHOULD allow Web-wide linking, not just internal document linking." )
