Feature request: tag default value (constant)

[GioF_71]

Hello Simon, thank you for the update.

I do not know if this feature should replace the existing one (Mytag.default={OtherTag}). I do not currently use this option, but maybe someone is.
A suggestion might be use two identifiers, like e.g.

Mytag.default -> to be use with other tag (as in current versions)
Mytag.constantValue -> new, to be use with a string with hyphens as you mentioned.

Of course if one specifies constantValue, that setting would override the 'constant' o trigger an error.

For my specific case, as I do not currently use .default, any solution would do just fine. Of course the choice is yours.

Thank you again for the feedback.
Please keep up with the excellent work!!!
