% Lexical Base Component B1ii:

% Morphoprosodic inventory

% For expository simplicity syllabic and prosodic nodes
% reduced to atomic nodes and are incorporated directly
% into the lexical entries.
% Lexical Base Component B2:

% Base event mapping templates with QLP operators

% Morpheme generalisation node with defaults.

% Syllable generalisation node with template, QLP operators
% optionality constraint, and defaults.

    <2> == <"<core>">              % Optionality constraint
    <no_core> == .                 % No second syllable

% Tone generalisation node with templates (atomic)

Tone:
    <> == "<tone>"                 % All 'normal' tones
    <tone> == 'L'                  % lexical default tone
    <1 'H'> == 'H'                 % propagated tone
    <1 'L'> == 'L'.                % propagated tone

% Core node with no analysis of internal core structure,
% but null as default for second syllable core.

Core:
    <> == "<core>"
    <core> == no_core.             % No second syllable core
