30  * This tag must include all others in a theme file. This is required to enclose
31  * all other tags in an HTML form while editing the page. Usually this tag is
32  * the first child of <code>&lt;body&gt;</code>:
33  *
34  * <pre> &lt;body&gt;&lt;cms:editor&gt;
35  * <em>... (html and other MeshCMS tags) ...</em>
36  * &lt;/cms:editor&gt;&lt;/body&gt;</pre>
37  *
38  * <em>Important note:</em> since a form can't be enclosed in another form, you
39  * must surround any other form in your theme with a &lt;cms:ifnotediting&gt;
40  * tag:
41  *
42  * <pre> &lt;body&gt;&lt;cms:editor&gt;
43  * <em>... (html and other MeshCMS tags) ...</em>
44  * &lt;cms:ifnotediting&gt;&lt;form action='youraction'&gt;
45  * <em>... your form ...</em>
46  * &lt;/form&gt;&lt;/cms:ifnotediting&gt;
47  * <em>... (html and other MeshCMS tags) ...</em>
48  * &lt;/cms:editor&gt;&lt;/body&gt;</pre>
49  *
50  * This way your form won't be displayed while editing.
