With the Page Tree Creator Ignore Macro you are able to retain tags when creating new documents with the Page Tree Creator. Just insert the tag inside the body of the Page Tree Creator Ignore Macro.
It is also possible to wrap other Confluence macros like this. In that case, the macro parameters won't be replaced and references will point to the same location as before copying.
Tags, you wish not to be replaced during creation of a new page, can be stored in the macro body.
There are no parameters to be defined for this macro.
