Note that in case you need to print the document, the summary has a numbered heading.

To prevent this issue, you may choose to not show the title and have the Description and the Summary section collapsed. Printing is then no issue since there is no heading.

Suppose you need to extract the sections Space Relation, Providing Spaces, and Collaboration Spaces to their own documents. This way you may have easier content reuse, you may collaborate easier if each content is created by another author, any you may reference the individual sections easier if they have their own unique URL.

Let's use the Section Doctype to create a document for each of the three sections we extract and the Transclude Documents Macro to integrate them with the original document.

A section document looks like this:

To create the same heading number as in the transcluding document, you need to set the number start (heading-number-start) to 1.0 and the heading starting level (heading-starting-level) to 2.

Now the section headings align with the numbers shown in the transcluding document.

The configuration for the second transcluded section requires the number start (heading-number-start) to be set to 2.0.

The rendered document would render like this:

As you may already have notices, the numbering of the section does still not align. Headings have no numbers per default.

To change this you need to apply a CSS style to your Confluence site configuration or to your space configuration. This CSS may be different according to your layout tool you employ.

Here is one way to achieve the heading numbering for the transcluding document and all its sections for a standard Confluence environment. Using a layout tool may make the issue much simpler.

h1#title-text:before {  
   counter-increment: h1;  
   content: counter(h1) " ";  
}

h1#title-text:before {  
counter-reset: h1 !important;
counter-increment: none !important;
content: "" !important;
}
