You might not want every cross reference in your document to become a link in WinHelp. You can choose to have DITA2Go delete cross references of a certain format, or convert them to text. For example:
[XrefStyles] ; xref format name = properties (Delete or Text) ; if omitted treated as link Heading & Page=Text Page=Delete
In this example, DITA2Go would render any cross reference that uses the Heading & Page format as plain text rather than as a link. DITA2Go would also delete any cross reference that uses the Page format.
