===Pre-orders===

In order to seperate categories of different orders we use pre-order categories. These are used to group similar higher order subcategories within their parent category. In general, ''Category:<N> <G> musicians'' is a sub category of ''Category:<N> musicians'', but so is ''Category:<N> <&lt;I>ists'' which is true for all genres "G" and all instruments "I". Therefore, to keep them seperate, we introduce two pre-second order sub-categories of ''<N> musicians'' which are: ''Category:<N> musicians by genre'' and ''Category:<N> musicians by instrument''. ''Category:<N> <G> musicians'' will now be a sub category of the former, and ''Category:<N> <&lt;I>ists'' will be a subcategory of the latter, and neither will be placed directly into ''Category:<N> musicians''. Similarly, pre-third order categories might be of the form ''Category:<N> <&lt;I>ists by genre'' as a subcategory of ''Category:<N> <&lt;I>ists'' and ''Category:<G> <&lt;I>ists by nationality'' is a subcat of ''Category:<G> <&lt;I>ists''.

Note that each first order category can have 2 pre-second order sub cats, but each second order category will only have 1 pre-third order sub cat because the second-order category itself is only missing one peice of information.
