Editing attributes of tag. 
Автор: Dan ShackelfordDuring a recent audit of my website for ADA (Americans with Disabilities Act) compliance, it was noted that the <HTML> tag was missing the country sub-code for the language attribute and missing the text direction attribute. I happened to find a way to set these attributes completely by accident while examining Website X5 Pro's language setting. However, it would be much easier for people like myself if the language setting could handle the country sub-codes and if there was a similar attribute setting for text/table direction. (These are both attributes of the <HTML> tag at the very beginning of a website's code.)
I know I could export the project files to a disk and then edit them using an HTML editor, but then if I change the website in WebsiteX5 Pro, I have to do the editing again.
Hello. I sent a notification about your idea to the company employees, expect an answer from them here in the comments.
Hi Dan,
I am not sure about whether the ADA compliance will be implemented, I did already report a similar idea some time ago, anyway I will report yours as well and let you know in case of news.
Thanks! Kind regards.
