Options/Optionals in Headers_Footers

    Pathagoras can process <<*Options* . . .>> and <<*Optional*. . . >> text blocks in a document's headers and footers, but with several (hopefully minor) restrictions as listed below:

•The options/optional block in the header or footer must be tied to a 'parent' block in the body of the document via a !groupname! 'Free-floating' Options and Optional text blocks (with or without their own set of prompts) will not be processed. (If you do not otherwise have a !groupname! link, just use an <<*AskOptions*!group!. . .>> or <<*AskOptional*!group! . . .>>

•While the !grroupname! tie-in is required, no other 'accessories are needed or allowed. So remove arguments and prompts: Use;
               <<*Options*!gn!*red fruit/yellow fruit/burgundy fruit>>
and not

•The block must be at the surface level of the header/footer. It cannot be inside of a text block inside of a header/footer. (If you need other elements in the header/footer that must be precisely placed, you can easily add a text block for those elements.  So long as the Options/Optional block is not itself located into that text block, it will properly process.

•You cannot use {simple options} (i.e., with the curly braces). Only robust <<*Options* . . .>> and <<*Optional*. . . >> text blocks will process.
