[Soc-2009-dev] Weekly report - Collada module

[Sebastian]

Hi Arystan,

thanks a lot for the bug report! We precompiled the regular expressions 
by intention to remove dependency to "pcre_compile" and to speed up 
overall processing time. I must admit that this sounds a little bit like 
an overkill but the code generation for XSD Schema automatically 
generates the statements.

We have to check why the precompiled statements failed :(

Sebastian
