Thanks for the context. Still, it does not explain the difference in behavior bestween doc() and parse-xml().
As far as I understand the XDM specification, whitespace may be ignored by the parser if there is a DTD or XML Schema that says that an element is not PCDATA (DTD) or mixed (XML Schema). In the absense of (support for) schemas, all whitespace should be left in. Wendell Piez writes it with many details. Whitespace in XML tricky. E.g. indenting XML cannot be done well without knowing which elements are PCDATA/mixed. Now that I know about the CHOP option, I can use BaseX predictably. And the legacy reasons for keeping it set are understandable.
