Vlan-Stack Trunk

I actually encountered this vlan-stack trunk command on a dell switch (not cisco I know).
What is the difference between using vlan-stack trunk instead of encapsulating it at two different interfaces?

When are you going to share the wealth with all the guys helping you do your job. You should be giving $5 to $10 dollars to everyone who post on your questions since every other day it something for your job and you haven't shared anything with the board like where you are located, the name of the company they are helping or going back down to the CCNET/CCNA forum and helping with a subnetting question or something.

What do you think the difference is? What has your research shown?

And yeah, consulting fees appreciated.

A vlan-stack trunk is a qinq or a vlan in a vlan.
But I dont understand how this command is different from doing encapsulation dot1q 2 times??

It is similar, but oh so different as to the affect that it has.
