make safecond unbound

It is a pleasure to me to inform you that
the DITA-TC has accepted the proposal to change 

 

Old: <!ENTITY % safety.content

                     
 "((%nosafety;) |

                        
(%safecond;))">

to

New: <!ENTITY % safety.content

                     
 "((%nosafety;) |

                        
(%safecond;)+)">

 

 

I am going to update the DTD, Schema and
the documentation.

 

Best regards

 

Chris
