+
+SL::GL - some useful GL functions
+
+=head1 FUNCTIONS
+
+=over 4
+
+=item C<get_active_taxes_for_chart> $transdate $tax_id
+
+Returns a list of valid taxes for a certain chart.
+
+If the optional param transdate exists one entry in the returning list
+may get the attribute C<is_default> for this specific tax-dependent date.
+The possible entries are filtered by the charttype of the tax, i.e. only taxes
+whose chart_categories match the category of the chart will be shown.
+
+In the case of existing records, e.g. when opening an old ar record, due to
+changes in the configurations the desired tax might not be available in the
+dropdown anymore. If we are loading an old record and know its tax_id (from
+acc_trans), we can pass $tax_id as the third parameter and be sure that the
+original tax always appears in the dropdown.
+
+The functions returns an array which may be used for building dropdowns in ar/ap/gl code.
