When creating a .qhp file based on the documentation at http://doc.trolltech.com/4.6/qthelpproject.html I set the namespace to be "thermite3d.org.Thermite.1.0". However, when I ran qhelpgenerator over it, it simply gives the error message: "Error in line 3: Namespace has invalid syntax.".

Through trial and error, I found that the namespace must be entirely lower case. Neither the error message or the documentation give any hint to this case restriction. I'd like it if the documentation made this restriction clear and the qhelpgenerator tool would give a mode detailed error message.

Thank you
