 You cannot group symbols on locked layers into a composite symbol,
but the layers may be locked after the symbols are grouped.
 You cannot delete a composite symbol that contains symbols on
locked layers, however, you can delete an unlocked layer.
 Normally, a symbol existing only on one layer is deleted if the layer is
deleted, but when the symbol is inside a composite symbol it is not
deleted. It stays in the composite symbol.
 If a composite symbol is hidden, all its parts are hidden. If the
composite symbol is visible its individual parts may still be hidden if
the layers they are assigned to are hidden.
 Since you cannot individually select the parts of a composite symbol
you must first use the Ungroup button to separate them in order
to change their layer assignments individually.
