    copied!<p>Is there any reason why <code>&lt;xs:group&gt;</code> cannot appear inside <code>&lt;xs:all&gt;</code>, but only inside <code>&lt;xs:sequence&gt;</code>?</p> <p>Let's see an example. Say, there is a list of tags (<code>&lt;a&gt;</code> to <code>&lt;d&gt;</code> and <code>&lt;e&gt;</code> to <code>&lt;f&gt;</code> - see example below) which do not appear in any particular order, but always wrapped into another object (either <code>&lt;foo&gt;</code> or <code>&lt;bar&gt;</code>); <code>&lt;foo&gt;</code>={<code>&lt;a&gt;</code>, <code>&lt;b&gt;</code>, <code>&lt;c&gt;</code>, <code>&lt;d&gt;</code>}; <code>&lt;bar&gt;</code>={<code>&lt;e&gt;</code>, <code>&lt;b&gt;</code>, <code>&lt;c&gt;</code>, <code>&lt;f&gt;</code>}:</p> <pre><code>&lt;foo&gt; &lt;a&gt;a1&lt;/a&gt; &lt;b&gt;b1&lt;/b&gt; &lt;c&gt;c1&lt;/c&gt; &lt;d&gt;d1&lt;/d&gt; &lt;/foo&gt; &lt;foo&gt; &lt;d&gt;d2&lt;/d&gt; &lt;b&gt;b2&lt;/b&gt; &lt;c&gt;c2&lt;/c&gt; &lt;a&gt;a2&lt;/a&gt; &lt;/foo&gt; &lt;bar&gt; &lt;e&gt;e3&lt;/e&gt; &lt;b&gt;b3&lt;/b&gt; &lt;c&gt;c3&lt;/c&gt; &lt;f&gt;f3&lt;/f&gt; &lt;/bar&gt; </code></pre> <p>I want to extract tags <code>&lt;b&gt;</code> and <code>&lt;c&gt;</code> into <code>xs:group</code> and use <code>&lt;xs:group ref="..."&gt;</code> when defining <i>complexType</i> of <code>&lt;foo&gt;</code> and <code>&lt;bar&gt;</code> in the XSD. However, due to the restriction mentioned above, this is not possible. </p> <p>What would you suggest as a workaround for the given problem? Chances are, I am doing something stupid, but again why is this incorrect?</p>
