   One link appears.

   Multiple links should appear, one for each language.

We probably don't do the right thing for rel="alternate" yet; this is definitely
multi-valued. I can't see how this works straight off; let's see if one of the
other coders on this toolbar can figure it out :-) It could be related to
hewitt's reformatting of the JS.

cool new feature!

I can reproduce this with the URL given, but
displays the correct number of alternate pages (two).
We used to DTRT for "alternate", but that got stripped out in one of the various 
rewrites.  It shouldn't be that hard to reassemble.  BTW, I'm attaching various 
link toolbar bugs to 87428 for convenience of tracking, even though that bug is 

Justin: I think you may want to use the "hreflang" rather than the "lang" 
attributes in your example...
Blocks: LinkUI
(/me reads W3C specs for LANG)
Hm! Did not know there was an hreflang attribute. I'll leave the page alone
until this bug is fixed, though.
This bug is either INVALID or an edge-case RFE. The reason Hixie's test case is
not working is because all the <link>s link to the same dummy page. I'm assuming
the Links Toolbar is noticing this and not adding them again.

You could argue that there's a case for changing the behaviour to add extra
links even if they are both rel="foo" and both href="bar.html" but that would be
an edge case RFE.

Chris: please don't spam all the people on bug 87428 by using it for dependency
tracking. That is not the way to use a closed bug. If you want to file a
meta-bug, please feel free to do so.

There is nothing in the spec that says that links pointing to the same URI should
in any way be considered related to each other.

If I have

   <link rel="alternate" href="foo" title="Gibberish Version">
   <link rel="alternate" href="foo" title="Disassociated Press Version">

...then it should work, showing two alternate versions. We already have a bug with
multiple bookmarks with the same URI being impossible, let's not repeat the bug
with the link toolbar... However, this is indeed a trivial bug! :-)

I've slapped up a quick patch for this, but I haven't tested it yet.

Is there another part of the implementation that depends on the items in the
toolbar having unique URLs?  Looks good to me if not.
Oops, missed a spot.  This should be fine for testing now (i.e., no js errors),
but I have no idea what it will do to the implementation...I'm waiting to test
until some of the patches in my local tree get checked in.
Looks good to me. I'll r= it when it's easier to test it (fewer patches in local

Gerv, can you give this r= now that 0.9.5 has branched?

Can you get one from sballard? :-) I will if there's no-one else.

Can someone give r= on this? sballard's been away...
r=gerv, presuming you've actually tested this.

The Target Milestone (0.9.7) is passed.  This bug should be retargeted.
There is a reviewed patch attached.  If it is still valid, perhaps just
sr= and a= are required?
choess: any progress on this? Should at least be retargeted to something later
than 0.9.7 no?
Keywords: mozilla1.0
I'm not going to try to get sr= until after we branch for 1.0.
