You are welcome.

No, z3c.rml uses "stop". It just does not complain about any superfluous 
attributes, such as "end". "end" is simply ignored. All this works well.

Unfortunately I could not reproduce this problem. I created a new test file 
tag-blockTableStyle-2.rml that demonstrates your use case and everything 
works fine.

While checking out your reports, I also updated the source code to ReportLab 
2.1 with which I tested everything. I have just released z3c.rml 0.6. 0.6 is 
tested with ReportLab 2.1 and includes the additional test.

Stephan
