Apply tags just for one headline?
<p>I have a global tags for tasks, but I would like a specific tags for projects that should not be applied to tasks. I tried using <code>#+TAGS:</code> under <code>Projects</code> headline, but those tags still apply to tasks. </p>

<p>EDIT.</p>

<p>My Current Setting:</p>

<pre><code>#+TAGS SCHOOL(S) HOME(H) PHONE(p) COMPUTER(c)
* Tasks
* Projects
#+TAGS ACADEMIC(A) PERSONAL(P) ADMINISTRATIVE(a) RESEARCH(R)
** Project A       :PERSONAL:
*** Project Plans
**** Task 1 for Project A 
**** Task 2 for Project A 
*** Project Support Materials
</code></pre>

<p>I wanted to confine second TAGS definition to subheadlines of <code>Projects</code> headline so that it won't interfere with the first TAGS definitions.</p>
