set promptnodtd
set promptnotdtd= { on | off}
When a document is loaded for which the DTD or Schema cannot be found and promptnodtd is set to on, the user is prompted whether to perform one of the following actions:
• Browse for the DTD/Schema.
• Edit the document in free-form XML mode.
• Edit the document as an ASCII document.
If promptnodtd is set to off, the use can only edit the document as an ASCII document. A document instance without a DOCTYPE declaration will be opened in free-form XML mode, without prompting if promptnodtd is set to off.
The default value of promptnodtd is on.
