Well, this is hardly an argument, 5 months cannot be expected to be anough to get some changes like XLink in. I also think the lack of readily pluggable XLink processors does not exactly encourage adoption of XLink in any spec (including non-W3C specs). It could be interesting to look at the details: XSLFO could use links/references for three purposes: - The external-graphics has a "src" attribute, quite similar to HTML img src. The object retrieved from the URL is to be displayed. - The icc-color-profile has also a "src" attribute, this time it points to a ressource which is used while rendering other stuff, a bit different in semantics from the above. - There is a quite explicit basic-link (but no non-basic link :-), which uses either an internal-destination (basically an IDREF if the FO's ids were IDs), or an external-desitnation (an URL). That'd be a prime candidate for some XLink stuff. If we are at it, XSLT also has "href" attributes on the xsl:include and xsl:import elements. Whether this is a case for XLink can be discussed. The more interesting case is the proposed xsl:document, which also takes a href, but this is the destination of the output. I'm not sure whether and how this would fit with any XLink semantic. Another important link is, obviously, the link from a document to a DTD. Yeah, this has been nailed down in the XML spec itself and is hardly up for a change. But there is also the recommended practice to link (sic) a document to a XSchema (or was it to link an XSchema to the document?) Anyway, from time to time the question of "How do I specify multiple DTDs/schemas/... to validate against?" crops up, and seems to be nicely solved by a multi target XLink...I can even see the dialog box pop up with the selection "Which schema do you want to validate against today?" :) Furthermore, I havn't had a look at encryption&signing for some time, but I vaguely remember there are links (well, references) to certificates and such as well. On a related note, there is an XInclude spec, and XSLT has its own xsl:include... didn't SVG also have its own include mechanism? And there are still entities... I hope this isn't too byzantine to everybody and somebody can link it all together... J.Pietschmann
