<dt>description:</dt>
<dd>Declares the base name for a tree of permissions. The application takes
ownership of all names within the tree. It can dynamically add new permissions
to the tree by calling <code>{@link android.content.pm.PackageManager#addPermission PackageManager.addPermission()}</code>. Names within the tree are separated by
periods ('{@code .}'). For example, if the base name is
{@code com.example.project.taxes}, permissions like the following might be
added:
<p style="margin-left: 2em">{@code com.example.project.taxes.CALCULATE}
<br/>{@code com.example.project.taxes.deductions.MAKE_SOME_UP}
<br/>{@code com.example.project.taxes.deductions.EXAGGERATE}</p>
<p>
Note that this element does not declare a permission itself, only a
namespace in which further permissions can be placed. See the
<code><a href="{@docRoot}guide/topics/manifest/permission-element.html">&lt;permission&gt;</a></code>
element for information on declaring permissions.
<dt>attributes:</dt>
<dd><dl class="attr">
<dt><a name="icon"></a>{@code android:icon}</dt>
<dd>An icon representing all the permissions in the tree. This attribute
must be set as a reference to a drawable resource containing the image
definition.</dd>
<dt><a name="label"></a>{@code android:label}</dt>
<dd>A user-readable name for the group. As a convenience, the label can
be directly set as a raw string for quick and dirty programming. However,
when the application is ready to be published, it should be set as a
reference to a string resource, so that it can be localized like other
strings in the user interface.</dd>
<dt><a name="nm"></a>{@code android:name}</dt>
<dd>The name that's at the base of the permission tree. It serves as
a prefix to all permission names in the tree. Java-style scoping should
be used to ensure that the name is unique. The name must have more than
two period-separated segments in its path &mdash; for example,
{@code com.example.base} is OK, but {@code com.example} is not.</dd>
