Having seen a few dependant or separate parchment seal tags, it's probably time to analyse the variety of slit patterns through which the seal tag was inserted. There are a number of variations, but while searching for these examples, I actually found that just two patterns of slits accounted for nearly all of the documents, and the few other slit patterns are rare differences.
One slit
The simplest slit pattern is to create a single slit in the parchment. The slit is standardly made in the folded up section (where the parchment is doubled), near the top of the folded section. That is the knife runs across the parchment once, but cuts both pieces of doubled parchment, ie one pair of slits. This is likely to be the strongest location for the slit, giving the most wear resistance. The example below shows both front and rear of a document, showing how simple the single slit is.

Here's another example of the same slit pattern, this time with the tag removed and the paper unfolded, and laid flat. We see two slits as this single slit was made through two layers of parchment at once.

In the final example of this pattern, the folded parchment has unfolded under the tag on the right (front - left on the back), and can be compared to the other tag which is threaded through the folded parchment. This shows the simple arrangement of tag and parchment and that there is no fixative or other fancy folding happening.

You may have noticed in the previous example, the tag on the left (front left) was not pulled down as low as it could be, but rather had been pushed up like a pop up book. Both this and the unfolding of the parchment might have been encouragement for high class scribes to develop more complex slit patterns that would better hold all portions of the document in place, as discussed in the next section.
Three slits
A pattern of 3 slits (3 sets when folded) is the other most commonly used way of threading a dependant parchment seal. The example below shows the near ubiquitous arrangement - as in the one slit, the first slit is made in the folded section, as close to the top of it as possible, cutting through both layers of parchment. The second slit is made in the centre of the folded section, also through both layers. The final slit is made through one layer, located on the fold of the document.

Slits: 3 slits, 2 through doubled parchment and one through fold
Tag: single piece of parchment
(Caen, AD Calvados, H 912)
While different threading patterns could be constructed with these slits, where the backs of the document can be seen, or details of where the rear portion of the tag emerges from the slits, the evidence I've seen all points to one pattern being in use. The tag begins inside the document at the top, threads out through both front and rear holes, then back in through the middle holes in front and rear, then emerges from the document through the slit on the fold. This sounds rather complicated, so I'll post a set of photos of how to do this soon. An example showing front and rear of a document in this folding pattern is below.

Tag: Folded tag passes through two slits in folded portion and one slit on fold of parchment
Seal: red wax seal, depicting a (woman's?) portrait, facing to the right.

While this isn't as easy to construct as other possible patterns, this is much more resistant to tag movement, holding the tag more firmly in place, with the two sides of the document providing double reinforcement for the document.
3 slit variants
I mentioned at the start that a few variations on the slit patterns exist. The first is to move the top slit to above the fold in the parchment. This can be done with a single slit or a 3 slit pattern, examples of both below. I expect this to be weaker than passing through both layers of parchment, which probably accounts for the rarity of this variation.

Another stranger variation to the 3 slits is shown below - the top slit is made above the fold and two slits are made in the folded section - none on the fold. It seems to have worked fine as an attachment method.

Given that this is just one of 3 tags done this way on this document, lets assume it was a mistake, and the tag was intended to pass through all the slits.
The mythical 2 slit pattern
In theory various combinations with two pairs of slits (or simply two slits in an un-doubled parchment) ought to be possible. The example below at first looks like 2 slits , but look carefully - the doubled parchment has been smoothed down. Turn it back up again, in such a way that it ends just a nice distance below the words and this example is actually a single slit pattern.

While I think a pattern with 2 pairs of slits should be possible, I still haven't found any examples yet, so I wouldn't be sealing any documents this way.
Other slit patterns
I'm yet to find any good evidence for any slit patterns not mentioned above. I'm sure if I find enough examples of sealed documents, something out of the ordinary, or some regional variant like the clever variations the Swedish made on integral tags will turn up, but the above certainly seems to cover the majority of examples. If you spot anything you think might be different, please let me know.
