Briefly: gtkdoc-mktmpl always puts a section title to template files.  While it
is possible to override the title in in-line docs, it causes warnings.

Less briefly (assuming normal gtk-doc setup, I'll use my real class names):

1. Create gwyserializable.h, gwyserializable.c source files with some interface
declaration.

2. Add/move section docs for GwySerializable in-line to gwyserializable.c:

/**
 * SECTION:gwyserializable
 * @title: GwySerializable
 * @short_description: Abstract interface for serializable objects.
 *
 * Blah, blah.
 **/

3. In documentation directory, remove tmpl/gwyserializable.sgml to be sure we
everything that's there is automatically generated.

4. Rebuild templates (runs something like: gtkdoc-mktmpl --module=libgwyddion).

5. Look at tmpl/gwyserializable.sgml, it has no field filled, except SECTION
Title that reads:

gwyserializable

6. [Re]build XML (runs something like: gtkdoc-mkdb --module=libgwyddion
--source-dir=../../libgwyddion --sgml-mode --output-format=xml).  It prints

WARNING: Documentation in template file for ./tmpl/gwyserializable:Title being
overridden by inline comments

----------------------

I haven't found any option or procedure that would avoid this warning -- except
for removal of the offending title (that could be done by a custom script in
tmpl-build stage, but...).
