Research direction

Start in htdp-lib/stepper/private/xml-snip-helpers.rkt, especially the code at the referenced lines 62 and 114-136, and trace how XML boxes are handled under BSL. Reproduce the current BSL XML-box failure and make the completed behavior report that XML boxes are not supported in BSL instead of exposing an unbound quasiquote error.

Written by the indexing model from the issue text.

Description

enhancement

XML boxes assume quasiquote, which is unavailable in BSL. However, they err with "quasiquote unbound" instead of something like "not supported in BSL."

This is in spirit the same as racket/drracket#722 and racket/htdp@aa2ad718. But, since this issue is discovered by testing and not reported in practice, I'm labeling it as a low-priority feature request.
