What is usage of parameter tag used in TabHost.newTabSpec
<p>May I know, for the following code.</p>

<pre><code>// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("The Artists",
                  res.getDrawable(R.drawable.ic_tab_artists))
              .setContent(intent);
</code></pre>

<p>What is the purpose of having "artists" tag as the parameter of <code>newTagSpec</code>? Should I use an internationalize string like</p>

<pre><code>spec = tabHost.newTabSpec(getString(R.string.artists)).setIndicator(getString(R.string.the_artists),
                  res.getDrawable(R.drawable.ic_tab_artists))
              .setContent(intent);
</code></pre>
