Hi all,
 
I just joint the mailing list.
 
I would like to ask you regarding the diagrams which are drawn using sml schema or dtd
 
1. Could any one  ever know any diagrams which are drawn using xmlschemas or dtd?
 
2. Could any one  ever know any Security Critical systems diagrams ( such as hazops, FTA,FMECA ,statecharts, architect draw,plant schematics diagrams ) which are drawn using xmlschemas or dtd?
 
 
3. Could any one suggest me references( URL or books) regarding how to draw diagrams using xml schemas or dtd?
 
 
Thank you very much in advance and looking forward for the replay
