While funny, I did not mean that. I meant to say that "the code
which processes the placeholder" does NOT know the range of
characters to escape but it still does escape them.

No.

Nearly. The code processing the placeholder calls whatever escape
function the code telling it to process placeholders (such as a
form template instance) tells it to. The template, in turn, "knows"
that it is XML based or LaTeX based or whatever else format it
needs to comply with.
