Hi Jeremy,
Thanks for taking the time to review, very helpful.

Yes, that is indeed obvious. My intention was to provide a quick visual
that that's indeed the case to provoke an "sure thing" effect.

Yes, thank you. I have moved it to the "general wikitext" section and
mentioned that it, of course, applies to a macro body just the same.
Similarly, listing <$widget param="$macroParameter$"/> as a way to pass

Good to know and be reminded that it's not just about widgets, but any html
element attribute. I have renamed that section accordingly

Yes, so that is actually an very good example which I have now added,
although surely important to know that the same does not work for macro
parameters.
I have restructured the whole thing now and put it here for reference...
general wiki text, including macros» <<variable>>» {{transclusion}}»
<variable>, "<variable>", [[<variable>]]general html element attributes,
including widgets, e.g. $macrocall» <$widget attribute=<<variable>>/>» <$widget
attribute=<<callMacroToComputeValue>>/>» <$widget
attribute={{transclusion}}/>» <$widget attribute="prefix-<<variable>>"/>»
<$widget
attribute=[[prefix-<<variable>>]]/>» <$widget
attribute="prefix-{{transclusion}}"/>within macro body» $macroParameter$,
"$macroParameter$", [[$macroParameter$]]» $(variable)$ (references a
variable from the context of the calling macro)» <$widget
attribute="prefix-$macroParameter$"/>» <$widget attribute=$macroParameter$/>
(unsafe
when having spaces)» $variable$, "$variable$", [[$variable$]]macro parameter
» <<macro param="$macroParameter$">> (only inside macro)» <<macro
<<variable>> >>» <<macro "<<variable>>" >>» <<macro param:<<variable>> >>»
<<macro
{{transclusion}}>>» <<macro param:{{transclusion}}>>in filters»
[$macroParameter$] (only filters within macros)» [tag<variable>] (no inner
square brackets!)» [tag{transclusion}] (only single curly brackets!)»
[tag[$(variable)$]]» [tag[$(variable)$]]
Best wishes, Tobias.
