    <p>Top-level Go code (<code>import</code>, <code>func</code>, etc.) must be
      enclosed within
      a <code>&lt;?go:top</code>&nbsp;&hellip; <code>?&gt;</code> tag.
      Anything declared top-level will be available
      within <code>&lt;?go:block</code>&nbsp;&hellip; <code>?&gt;</code>
      and <code>&lt;?go:expr</code>&nbsp;&hellip; <code>?&gt;</code> tags on
      the same page.</p>

    <blockquote>
      I just wanted to say, <q><span class="hello"><?go:block SayHelloFrom(gospOut, "Go Server Pages") ?></span></q>
    </blockquote>

    <p>In this example, we placed
      the <code>&lt;?go:top</code>&nbsp;&hellip; <code>?&gt;</code> tag in the
      HTML <code>&lt;head&gt;</code>&nbsp;&hellip; <code>&lt;/head&gt;</code>
      section, but this is not mandatory.  It can appear anywhere on the
      page.</p>
