% 1 the attributes

% By three attributes do we determine the document structure.
%
%   One for marking the current structure element:
%   - is the index of the lua-side se table
%   - assignments are always local
\newattribute \tagging:current:se  \tagging:current:se = 1
%
%   One for ordering children of structure elements:
%   - assignments are always global
%   - should generally increase monotously
%   - should change (increase) at every se boundary
\newattribute \tagging:element:order \tagging:element:order = 1
%
%   One for marking the status:
%   - assignments are generally local
%   - if set, disables tagging and content marking in pre_shipout
%   - values &gt;10 indicate artifacts
\newattribute \tagging:current:status \tagging:current:status = \unset
%
%   A fourth attribute keeps track of the current language
%   - assignments are local
%   - sets language of structure elements
\newattribute \tagging:current:language \tagging:current:language = \language
