TYPO3 adds the TCA columns and the database columns of the language
fields since v13.3, so an integrator sets only the properties in the
ctrl section and places the fields in the form. The page taught how to
define the columns, with examples that claimed to come from the TCA of
tt_content, which no longer defines them. A link to
transOrigDiffSourceField read languageField, and the section about
transOrigPointerField called it the first field.

The example now comes from the conference extension of the TCA
Reference. A copy of its conference table is in
Documentation/CodeSnippets, which the screenshot instance installs, so
that the example is tested on every run. A screenshot shows the form of
a Spanish conference with the English title below the field.

A functional test installs the extension, and checks that its TCA needs
no migration and that its labels exist. make test-extension runs it,
and CI runs it on every push. The test found that TYPO3 v15 requires
the version and providesPackages in the composer.json of an extension.

The title "TCA, DataHandler, and FormEngine" named three parts of
TYPO3 that a new reader does not know. The page is now named after its
task, and it explains the TCA and the DataHandler where it uses them.

The option of the page properties is named "Hide default language of
page", not "Hide default translation of the page". The global setting
hidePagesIfNotTranslatedByDefault belongs to the configuration of the
installation, not to the ext_localconf.php of a site package.
