Description

attempting to include the TOC using a markdown file. If you have any headers past level 3, the TOC fails

using maven site plugin version 3.6, which looks like it's using doxia 1.7.4a
I c&p'd http://svn.apache.org/viewvc/maven/doxia/doxia/trunk/doxia-modules/doxia-module-markdown/src/test/resources/macro-toc.md?view=markup&pathrev=1716285#l2
however no TOC is outputted on a test.md.vm file.
If I change the file name to test.md (dropping the vm extension), I get a stack dump. "EmtpyStackException" when rendering this file. Not sure what I'm doing wrong
