ValidationMessage for collection

See original GitHub issue

i validate a collection of strings to match some regex, and i want to show the error messages connected to the collection with the <ValidationMessage /> component. The errors are connected with property with index InputTagNames[0] but i can not get <ValidationMessage /> to map into that.

in the below image, the two rules that are highlighted are the implementation i wished to use but that i can not use. and below is my workaround with custom validation. The custom validation workaround loops the collection and add a ValidationFailure to the context, where i am able to set the property name to be the name of the collection, so when i display <ValidationMessage For="@(() => Model.InputTagNames)" /> it shows up correctly

Is there a better way i can map the collection to the ´<ValidationMessage />´?
