Hello!

I was investigating the EFI_CONFIG_KEYWORD_HANDLER_PROTOCOL and it
looks like the syntax for the <KeywordRequest> listed in the UEFI
specification is not fully supported.
(Unified Extensible Firmware Interface (UEFI) Specification Version
2.9 March 2021 - 35.2.1.6 Keyword strings)
For example "KEYWORDINFO=" syntax is not working for me and I can't
see its support in the
https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Universal/HiiDatabaseDxe/ConfigKeywordHandler.c
I've tried to search https://bugzilla.tianocore.org/ for this issue,
but haven't found anything.
What subset of the <KeywordRequest> is currently supported?

Best regards,
Konstantin Aladyshev
