A reminder of something to come
Place a TK reminder at a point where something's not yet ready to be added.
A placeholder is enclosed within a matched pair of graymark delimiters, opening with a slash-question-mark /? and closing with a question-mark-slash ?/.
The placeholder itself is everything between the graymark delimiters.
Placeholders may have an assignee, which is a full-stop followed by a person's name. Spaces are not allowed in the assignee. The assignee is optional, but when used, it must be placed at the start of the placeholder.
Graynote placeholders may be embedded into the text area of any type of phrase.
Placeholders may span multiple lines.
Nested graynotes are not allowed.
Any whitespace before or after the graymark delimiters are preserved.
Graynote placeholder syntax is a formal way to communicate between the various professionals (artists, data analysts, indexers, etc.) assembling the document.
