The blog entry headers aren't dokuwiki markup headers, but <hx> elements 
generated by the plugin.  I did look at writing a plugin to allow markup 
in headers. I gave up after realising it would be extremely difficult to 
support TOC entries at the same time. 

Tech summary:
the CDATA between the header open/header close markup needs to be passed 
to the TOC handler.  That currently occurs at the end of the handle 
process and before rendering starts.  To know what is CDATA and what is 
not, all the markup between header open/header close needs to be 
rendered, only then is it possible to recognise the CDATA.  That means 
for each header instantiating a new parser/renderer. Currently in 
Dokuwiki that is an expensive exercise, I believe attempting something 
like that would put page generation times up significantly - so much so, 
that I didn't think it was worth attempting to complete the plugin.  If 
someone were to rewrite the parser to allow nesting without complete 
re-instantiation then it might be feasible.  :-)
