I recently noticed that the ampersand character & seems to be ignored in the caption of a parameter, although it shows up properly in the caption or text of a heading.

Try something like

    heading
        caption = "this & that"
    endheading
    float param p
        caption = "this & that"
    endparam

When the formula is invoked, the & shows up in the heading, but not in the param caption.

Maybe because it's a Boolean symbol, which would not be appropriate in a caption? Although that wouldn't explain why it shows in the caption of a heading...

An interesting point, but other special symbols, such as !, show up in captions.

I just tried it in the title of a formula. It doesn't show there, either.

This is because & is a special symbol on Windows to denote shortcuts. It should be escaped though so it shows up correctly, and I'll make a note of that.

Using && works, shows up as & when used in a caption.
