Yes, there is no such simple classification on the demo server.

I have setup a second proxy for the official server so you can test your
code. Its URL is:

Yes, exactly like this.

In fact, if you want to do a proper display, you'd rather strip the
'xxx: ' part and display just the tag label.

For example, if we have tags:

 - #1: 'a: Tag1'
 - #2: 'aa: Tag2'
 - #3: 'b: Tag3'

And question #0: 'A good question' with tags #1 and #2, you can have
different displays:

 1. A tree of tags, following the alphabetical order of 'xxx:' parts:

    +-- Tag2
    |    +-- Question #0: 'A good question'
    +-- Tag3

 2. You can make a flat display of all the tags:


  Selecting/searching one or more of them would selection corresponding
  question (current hard client behaviour). E.g., selectiing Tag1 or
  Tag2 would display question #0.

 3. Whatever other classification you find interesting, with user
    preferences, etc.

As a main rule, the demexp classification is /flat/: there is no
hierachy of tags. The client is supposed to offer means to explore this
bag of tags. 

On this flat bag of tags, we have added a kind of /default/ hierarchy
which might be used but is not by any means mandatory.

Use what you feel interesting for you. Feel free to experiment! ;-)
