Describe the bug
Trying to use \doxyconfig to circumvent the restriction of \internal command (which doesn't span over sections):

doxyfile:

INTERNAL_DOCS = YES
ENABLED_SECTIONS = INTERNAL_DOCS_YES

and my mainpage.md:

\if INTERNAL_DOCS_\doxyconfig INTERNAL_DOCS

Some internal documentation

- should be shown if INTERNAL_DOCS == YES
- but always not shown because \doxyconfig seems not to work when used as an if-argument

\endif

To Reproduce
s. attached zip file:

Test35_doxyconfig.zip

Expected behavior
May be this is the intended behavior; but I think it should work as an if-argument, too

Version
Version 1.14.0

Additional context

• \doxyconfig expands successfully in various use-cases (s. example)
• The documentation says: "...as used in Doxygen's configuration file...": Because first I run in little trouble it may be helpful to clarify something like: "...i.e. \doxyconfig doesn't expand to the respective default value but to an empty string if <config_option> not used in the configuration file"
