Kind of unwieldy in the case of multiple frames with the same name,
isn't it?

Nope. It's indexing of frame arrays, as per NetScape's documentation.

The idea here is that name references in a framesetting document's URL
can be indexes into frame arrays, followed by the URL. Each frameset is
referenced through its parent. Here's a better example:

A framesetting document http://main/frame.html creates three frames.
These frames are indexed relative to the window as frames[0],
frames[1], and frames[2]. At this point the URL for this page is simply

A link is selected in frames[0] that loads frame2.html into frames[2].
The bookmarking URL has now become


since to reproduce the current state of the document, the UA simply
loads main/frame.html normally and then loads frame2.html into

Let's say frame2.html is also a frameset document that splits frames[2]
into two subframes, which can be considered as frames[2][0] and
frames[2][1]. A link is selected in frames[2][0] that loads
frame2-1.html into frames[2][1]. The bookmarking URL now becomes


And so on. It doesn't strike me as that difficult to keep track of
which URLs are necessary to reconstruct the current state of the
window. And certainly the index notation is far more compact than
trying to track frame names that may be duplicated.

I see the problem when the URL already has a name reference attached -
particularly if the named reference starts with '[', but this isn't a
formal proposal, just a suggestion that will not break current
