In the old versions of the XyMacro book the macro 'primitives' were indicated with an asterisk symbol or *.
In the newer versions of the same manual this indication has disappeared and now there is no more way of knowing if a macro is a primitive or not.
Which is a nuisance and also a danger when writing macros.
Calling primitives directly as a primitive using the </ ..> syntax prevented you from having another macro somewhere that accidently had the same name as the primitive and that was overwriting the meaning the primitive by accident.
So please bring back the asterisk notation...both in the index at the end of the xymacro book and in the regular pages explaining the use of the macro.
