It just has to make the linked-to object visible. Just to clarify, by "linked-to object" you mean the element bearing the specified id element and not just the whole document, right? Because from my reading of "17.2.2 SVG fragment identifiers", there is no requirement to make the id-element (the fragment identifier) visible. It says: "If the SVG fragment identifier addresses any element other than a 'view' element, then the document defined by the closest ancestor 'svg' element is displayed in the viewport using the view specification attributes on that 'svg' element." So, if you have a link to 'myfile.svg#myId', if the nearest 'svg' element to 'myId' is the root, and 'myId' is a rect at, say, y='1000' and is outside the viewport/viewBox, it won't be visible. Personally, I think that the SVG Spec should specify that 'myfile.svg#myId' is assumed to be an implicit view that includes the id-element. Much more intuitive, and the outlier cases are miniscule. When *wouldn't* you want such behavior? Of course, if the element doesn't have a rendered bbox (say, in the case of display='none'), it shouldn't attempt change the viewport. | DS> All of these behaviors are specified for the 'SVG view | DS> specification' [2], using syntax like | DS> MyDrawing.svg#svgView(viewBox(0,200,1000,1000)), but as far as I | DS> know, no viewer has yet imlemented that. | | Its implemented by Batik and by CSIRO. | | (Of course, it could have been implemented by ASV and Corel | too, in theory, but we wouldn't know because of the browser | those are hosted in). | | DS> This is a real pity, because that rocks.

"Batik," you say? I'll have to write that one down... ;) I've got to confess, I didn't check Batik, because I concentrate mostly on common Web browsers for tasks like this. I meant that it's unimplemented in ASV, Firefox, and Opera. Thanks for setting me straight. It does work, as you say, in Batik, but there's a bit of odd behavior... in the location bar, the fragment identifier is doubled. For instance, svg2.svg#svgView(viewBox(200,200,100,100)) becomes: svg2.svg#svgView(viewBox(200,200,100,100))#svgView(viewBox(200,200,100,100)) No big deal, but I guess I'll file a bug report.

Its a limitation of the Win IE plugin architecture - fragment identifiers are stripped from the URI before sending to the server (this is correct) and the fetched local copy of the content is given the stripped, fragment-less URI instead of the real one (this is broken). Its been reported since IE4 and has been promised to be fixed several times but never is. I would be very surprised if IE7 fixes it.

RE: [svg-developers] accessing anchors inside a svg
Hi, Tom- Unfortunately, you are bumping into a limitation of the available viewers, and possibly a problem with the language. Your example has a flaw, too. I've encountered this before, and have an example [1]. Problem 1: Fragment identifiers (myurl.ext#fragmentID) in IE+ASV get lost when you are working locally. So, you can link to a Web-based resource, but not a local one. This problem doesn't exist in Firefox. Problem 2: There is no specified behavior for how fragment IDs are to be treated in SVG. There are many options (it might translate the view so that the element is in the top left of the screen, or the exact center of the screen, or just enough so that it is visible, or it might even change the viewBox so that the element fills up the screen). All of these behaviors are specified for the 'SVG view specification' [2], using syntax like MyDrawing.svg#svgView(viewBox(0,200,1000,1000)), but as far as I know, no viewer has yet imlemented that. This is a real pity, because that rocks. Man... No, instead, all viewers I know about simply ignore the fragment-id. This does not prevent you from creating a script solution that gets the document location, extracting the id, and changing the viewBox yourself; I've done that before, but I can't find my example just now. Problem 3: This is minor, and isn't the source of your woes, but an ID attribute cannot start with a number; it must start with an alphabetic character. That being said, you don't need the elaborate XPointer syntax: is equivalent to: [1] See: http://svg-whiz.com/svg/xlink/ Start here: http://svg-whiz.com/svg/xlink/jumpToId.svg [2] http://www.w3.org/TR/SVG/linking.html#LinksIntoSVG Sorry to be the bearer of bad tidings.
