Error while using the UK SDC Documenter as a Post build event

We were contacted by Brent Anderson from RBA Consulting. He ran into some errors while using the UK SDC BizTalk 2006 Documenter as a post build event.

Error initialising documentation publisher
Brent found out that using the documenter in a post build event works fine, as long as you just use the /def[ault] parameter.
When we tried to use the /o[utput] parameter (to set another output directory), we were confronted with an 'Error initialising documentation publisher'. We also tried other parameters, but that resulted in the same error.

Solution
After some research we found out that when you want to use other parameters, than the /def[ault] parameter, you must supply the /p:chm parameter to make sure the document publisher can be initialized.
