 * This is a register macro template defining a local value particular to :that value is substituted for template logic that might alternatively be stated as

This is frequently a more elegant and less cumbersome means of implementation, that eliminates many if-then-else parser function situations in interwiki capable templates, and is especially valuable within #switch and other #if-then-else blocks of code.

 * On Wikipedia this register holds the value of a null... ':', enabling interwiki templates to show local redlinks, instead of always being cast as a fullurl type of link as local use of Pagname would otherwise generate... hiding and masking an error or bad link.

This different method of implementation has instead a hardcoded different fixed value on and off the current sister site when accessed by the identical template on various sisters. This implementation avoids multiple usages of #ifeq: SITENAME testing, by substituting a locally defined value which correctly settles the issue involved in the main (usually an interwiki type of linking) template logic.
