A schema's property or value type list, or a value type's field list,
written more than once is read each time; and a pdfaExtension:schemas
that isn't one rdf:Bag (TechNote 0009, 4.2) is reported.

A qualified value has exactly one rdf:value; a parse type other than
Resource, which XMP doesn't use (ISO 16684-1 7.9.2.5), breaks the value;
and an rdf:resource element holds no element content in any form.

All five extension schema container namespaces are written with their
own prefixes, pdfaExtension included (PDF Association TechNote 0009,
4.1). The module comment cites TechNote 0009 section 4 for the schemas,
entries and prefixes, and says where PDF/A-2 asks more than it does.

Every pdfaExtension:schemas description needs its entries: a schema its
schema, namespaceURI and prefix; a property its name, valueType,
category and description; a value type its type, namespaceURI, prefix,
description and field; a field its name, valueType and description.
Each description namespace is written with its own prefix. One pass over
the metadata streams serves this check and the value types.

Qualifiers beside an rdf:value that are predefined properties keep their
types; rdf:value may be an attribute of an empty property element; an
rdf:resource element is empty; and character data around array items or
in an rdf:Description structure breaks the value, as it already did in a
parseType="Resource" structure.

The TIFF, EXIF and Additional EXIF namespaces come from the September
2005 XMP Specification that PDF/A-2 cites ("EXIF Schemas", pages 58-70),
with its EXIF value types (pages 83-87): Rational as numerator/
denominator, GPSCoordinate as DDD,MM,SSk or DDD,MM.mmk, and the Flash,
OECF/SFR, CFAPattern and DeviceSettings structures.

A metadata stream is decoded by its byte order mark (UTF-16 big- or
little-endian, or UTF-8; ISO 16684-1 7.3) before it is parsed. A GUID
is a simple value but not a URI (ISO 16684-1 8.2.2.3), so the
document and instance IDs of xmpMM, stRef and stEvt don't take
rdf:resource.

* fix(ui): About credits tables fit without side-scrolling and their columns resize
The Contributors table and the Models table were egui Grids inside a
two-way scroll area: they opened wider than the dialog, so they scrolled
sideways, and Company and Model sat almost touching. Both are now
egui_extras tables. Each column opens at the width of its header and widest
cell, the spare width goes to the text columns (Name; Company and Model),
and every column edge can be dragged. Widening a column grows the table
like a spreadsheet, and only then does it scroll sideways; the header stays
put while the rows scroll. Counts and dates are right-aligned and every
cell is vertically centred.
The sorted column stays highlighted and its direction shows on the
toolbar's sort-order button, so headers no longer reserve room for an
arrow. The opening widths come from fit_widths, a pure function with unit
tests that a fitted table fills its room exactly and that only the text
columns give way when room is short.

* Let every credits column be dragged, and refit changed tables
The last column was egui's remainder column, which has no drag handle, so
it could only be resized from the edge before it. It is now an ordinary
column with its own handle.
A table keeps its column widths, so switching to a longer name left the
Name column at its old width and clipped the text. The table now goes
back to the opening fit whenever that fit changes: a longer widest cell
or a resized window. Dragged widths are dropped at that point.
fit_widths could overflow the room when one column hit the minimum,
because the other columns did not take up its share. Columns now give
way in proportion to their width above the minimum.

* Refit credits tables on what they measure, not the fitted widths
Comparing the fitted widths missed the case it was meant for. Name is the
only growing column, so a longer name takes its extra width from the
spare room and the fit comes out the same: a dragged Name width stayed,
clipping the longer name.
It could also drop dragged widths by accident. The fit comes from the
available width inside the scroll area, which scrolling can nudge, so
scrolling a widened table could reset it.
The table now compares the natural widths and the clip rect's width,
which scrolling does not move.

Every metadata stream is read, within one decode allowance, not only the
catalog's. Predefined properties inside a Pantry item keep their types;
rdf:value may be an attribute; rdf:resource makes a URI, which only a
text type takes; a value's text is all its text nodes; an array item is
rdf:li; a parseType="Resource" structure has no character data; a time
zone is Z, +hh:mm or -hh:mm; and a value nested past every type's depth
doesn't have its type.

Properties of the Dublin Core, XMP Basic, Rights Management, Media
Management, Basic Job Ticket, Paged-Text, Dynamic Media, Adobe PDF,
Photoshop and Camera Raw namespaces must have the types ISO 16684-1
clause 8 and XMP Specification Part 2 give them: simple values by their
lexical form, arrays by kind and items, structures by their fields, in
every RDF/XML form a value can take. xmp::parse is shared with the
identification read.

main's 3D-embed change (#5808) added crates/annot/src/threed.rs with its own
pub MAX_MODEL_BYTES (same 256 MiB value), so both were re-exported from the
crate root and pdfcraft-annot no longer compiled after merging main. model3d
now uses threed's constant.
