For the context params, the docs say it is best to use the content.* variations

* content.id, content.version, content.type, content.plugin
* space.id, space.key
* page.id, page.version, page.type DEPRECATED

NOTE The page.* variables are available, but have been deprecated in favor of their content.* counterparts.

However, for static content macro, the variables are the page.* variant (https://developer.atlassian.com/static/connect/docs/latest/modules/confluence/static-content-macro.html)

Feel this is quite confusing as on one hand it's deprecated, but on the other it's the only option available. (Got bitten by this when I changed the page.id to content.id for the macro definition and everything broke)
