As an example, say I would want to change the filter navigation for categories to add a
title attribute to the links generated. The file
contains the category object (
$_category). However, the attribute
meta_title isn't loaded for that object.
Straight forward, I could load a second category object, but that loads a lot of attributes that
$_category already contains.
So I'm looking for the most lightweight way to load additional attributes for a given object, and best would be without loading a new object of the same type.
