DB & Dev Tools · Data formats: YAML lists at their key's indent, XML entities

YAML reads a list written at its key's own indent, as manifests do, and
a list at a map's indent ends at the next key. A `#` inside a quoted
scalar is no comment. XML reads entity references in text and
attributes, failing on one it does not know, and a text's path counts
text nodes from one. A tree's note takes at most half its row, cut with
an ellipsis, so a long value or attribute leaves the key its name.
Format and Minify fail loud if pressed while the JSON does not read.
