Exclude generating table of content from within a excerpt-include macro?

[Ralf Brinkmann]

Our documentaion in confluence has some kind of fixed layout regarding the heading.

I.e.
1. Common
2. System Design
3. Application
4. Access to buildings

In several of these chapters we use the "excerpt-include" macro to include existing web pages. How ever, these included pages often have there own heading, which is seemless included, and that messes up the heading structure of the parent document.

Is there a way to avoid the "integration" of the headings from the excerpt-included document into the parent document?
