Hi, I have the following example code fragment: namespace boost { namespace detail { /** documentation */ class implementation {}; } // namespace detail using detail::implementation; } // namespace boost I'd like to have the class `implementation` show up in the Reference section generated by doxygen+docbook-xsl+boost build+docbook+... . Issue is, every namespace which name contains the string "detail" is excluded somehow. The direct output of doxygen has it, but not the docbook version. I couldn't find any EXCLUDE_SYMBOLS setting (it's not set in the doxyfile)or anything relevant amongst the docbook-xsl params or in the boost build scripts. Google search term "doxygen ignores detail namespace" and the like did not help. Adding documentation to the using statement and/or TYPEDEF_HIDES_STRUCT did not help. Thanks, Benedek
