Section numbering supression not working

[AlanKearns]

I have a global (print and HTML) stylesheet containing

Code: Select all

h1.nonumber, h2.nonumber, h3.nonumber, h4.nonumber, h5.nonumber, h6.nonumber
{
	mc-heading-level: 0;
	mc-auto-number-format: '{ =0}';
}

Called by a print stylesheet (via @import "global.css";) containing

Code: Select all

h4
{
	mc-auto-number-format: 'GH:{n}.{n}.{n}.{n+} ';
	mc-auto-number-position: outside-head;
	mc-auto-number-offset: 19mm;	
	mc-heading-level: 0;
}

and nothing in the h4.nonumber class.

I'm finding that h4.nonumber headings are being numbered like '1.0.0.1', on the page, when I was expecting them to be both omitted from the TOC and unnumbered on the page. Can anyone suggest what I'm missing?

The plot has thickened. It only happens on projects run through madbuild. The styles as shown above work within Flare.
