@spottedmahn Thanks for bringing this to our attention. Your feedback has been shared with the content owner for further review.
I understand the issue. I don't think this article is the appropriate place to describe the HTML schema. I have opened a workitem to investigate whether tags should be documented in a reference article.
Hi David 😊

fair enough

Great 👍. IMO, it seems pretty critical to tell people what they can or can't do when customizing the UI.
@spottedmahn Thanks Michael. Always appreciate the feedback!
A workitem is open in the engineering queue to document this reference information and they are currently working on it.
nice 👍

Hi @davidmu1 - was anything released on this topic?
Also wondering if anything has been released on this topic as I cannot find information within the B2C documentation for the filtering that is being applied.
Also, please see a related open question on why the 'for' attribute is being stripped.
