The format-only part of DesignCraft's crates/idml (at 513f77b8): the bounded, lenient package
reader, designmap includes, the package writer, the <Properties> accessors and the attribute
value codecs. DesignCraft's own XML tree is replaced by craft-xml, which adds node and attribute
caps per part. crates/textimport/src/tagged.rs moves as craft_idml::tagged behind a neutral
model of paragraphs and runs.
