/**
 * Parsing of the document XMP metadata packet (`META-INF/metadata.xml`).
 *
 * InDesign records, for every font the document uses, an `xmpTPg:Fonts` bag of
 * `stFnt:*` descriptors — crucially including the ORIGINAL font file name on the
 * author's disk (`stFnt:fontFileName`). That file name is the reliable link
 * between a required font and the binary shipped in a package's `Document
 * fonts/` folder, since the folder file name (e.g. `DINBd_.ttf`) rarely matches
 * the family name (`DIN-Bold`). Example entry:
 *
 * ```xml
 * <rdf:li rdf:parseType="Resource">
 *   <stFnt:fontName>DIN-Bold</stFnt:fontName>
 *   <stFnt:fontFamily>DIN-Bold</stFnt:fontFamily>
 *   <stFnt:fontFace>Regular</stFnt:fontFace>
 *   <stFnt:fontType>TrueType</stFnt:fontType>
 *   <stFnt:composite>false</stFnt:composite>
 *   <stFnt:fontFileName>DINBd_.ttf</stFnt:fontFileName>
 * </rdf:li>
 * ```
 *
 * `stFnt:fontName` is the PostScript name and joins to `Resources/Fonts.xml`'s
 * `Font/@PostScriptName`; `stFnt:fontFamily` + `stFnt:fontFace` join to
 * `FontFamily/@Name` + `Font/@FontStyleName`. Both joins are exposed via
 * `IDML.resolveFontFile()`.
