Altova XMLSpy 2026 Professional Edition

The DTD/Schema | Include Another DTD command allows you to include another Document Type Definition (DTD) or external parsed entity into the internal subset of a document type definition.

 

The effect of this command is to (i) declare an external parsed entity and (ii) include that entity at the cursor point:

 

<!ENTITY % navigation.dtd SYSTEM "S:\xml\navigation.dtd"> ....... (i)

%navigation.dtd; .................................................(ii)

 

The command opens the Assign File dialog to let you specify the DTD file you want to include in your DTD.

 

Note: This command is enabled in Grid View only.
