How exactly is Luxembourg a tax haven and why is it so popular?

[hernanday]

I was reading an article saying that Luxembourg is basically one of the top tax havens by assets, and number 2-3 for Canadian resident's/wealthy.
I'm curious why/how this is so, it seems to have relatively high taxes for a "tax haven", moderately high corporate taxes, interest and personal income tax, what am I missing?
Why is it more popular than places with literally zero taxes?

Is there a particular part of the article I should be looking at?

The article is not Luxembourg specific but talks about the biggest offshore financial centers that are baiscally used by multinationals to ship profits.
