<?blockfnctrl>
Description
This command specifies a control stream to be used for footnotes in a block. It can be used in conjunction with <?blockcolres>, which will reserve the relevant columns for the placement of sidenotes.
Syntax
<?blockfnctrl fnctrl:s>
fnctrl
Name of footnote control stream, in double quotes
Additional Information
When a footnote control stream specifying sidenotes is applied to a block, the columns of the block will behave like the columns in a frame.
If a footnote reference is processed inside a block and that block does not have a footnote control stream, then the footnote control stream of the frame containing the block is applied. Similarly if a footnote is placed in a nested block which has no footnote control stream, then the parent’s footnote control stream is used, if it exists, else that of the frame.
