The application can also create a custom DocumentLinkTarget that does not exist in the document and call RunLinkTarget manually.

In all cases, the following is performed:

If the value of PageNumber of linkTarget is 0, then the current page is not changed, otherwise, if the value is not a valid page number, an exception is thrown.
