Markup declarations

In addition to tag markup, you can also include markup declarations in your source files to define other, related information. Markup declarations are control statements that specify how other markup (such as tags) within a source file is to be interpreted.

For example, in order for the compiler to recognize your source files as being intended for DTL conversion to ISPF elements, you must include a document type declaration at the beginning of each source file.

Like tags, markup declarations must be enclosed within a set of delimiter symbols so the compiler can distinguish the declaration as a control statement. All markup declarations are preceded by the <! symbol and followed by the > symbol.

Note: For multicultural support users of DTL the <! symbol can be replaced with the <: symbol.

DTL supports three types of markup declarations:

Document type declarations
Comments
Entity declarations.
