Conversion can lose comments, aliases, element order or native date types. Numbers that cannot retain their precision are rejected; quote them as strings. TOML requires a top-level object and cannot represent null. XML needs one root element, @ attributes and #text. Leaf text whitespace is retained; mixed content whose ordering cannot be preserved and DTD/entity declarations are rejected.

How to use this tool
Use @ for attributes and #text for text nodes; validate against your destination schema separately.
When not to use it
The builder cannot infer namespace contracts or preserve an original XML document's bytes.
