Providing default values for FlexForms attributes
------------------------------------------------

When a new content element with an attached FlexForm is created, the
default values for each FlexForm attribute is fetched from the
:xml:`<default>` XML attribute within the specification of each
FlexForm attribute. If that is missing, an empty value will be
shown in the backend (:ref:`FormEngine <FormEngine>`)
fields.

While you can use TypoScript :typoscript:`TCAdefaults` (see
:ref:`TCAdefaults <TCAdefaults>`) to modify defaults of usual
TCA-based attributes, this is not possible on FlexForms. This
is because the values are calculated at an earlier step in
the core workflow, where FlexForm values have not yet been
extracted.
