ZF-11730: Incorrect method name in title - Using the static staticFilter() method
The title of the section "Using the static staticFilter() method" is incorrect as the actual method discussed is filterStatic(). I'd argue minor rather than trivial as some people may skim through the documentation for the name of a method they cannot remember and not read the entire paragraph.
Also, and this may be a different issue, why does it need a different name from the non-static method? Can the method not be written to work out if it is being called from an instantiated class or not - ala singleton pattern and either behave as static or not as needed? I can't see any reason for the 'static' naming convention in the ZF coding standards.
