cfm-footnote
The cfm-footnote Confluence macro is converted to some syntax which a standard installation of XWiki provides.
What to use in XWiki
The corresponding XWiki feature is the footnote macro. It has the limitation of only supporting inline content, contrary to the Confluence macro, which can contain block data.
See Footnote Macro.
Import details
Note that this macro is coming from confluence cloud. The datacenter/server version is footnote.
Because of technical limitations, it is hard to convert the Confluence footnote macros to the XWiki footnote macros.
The macro is converted to the group syntax, replacing SomeID and SomeClass by the actual values in the Confluence macro parameters id and class:
(% id="SomeID" class="confluence_cfm-footnote_content SomeClass" %)
The content is set from the text parameter.
