This is my second post about section 508. This time it's related to asp-server control Menu.
There are 2 attributes such as DynamicPopOutImageUrl and StaticPopOutImageUrl which is often used for building a Menu. Both of these attributes MUST be accompanied by another 2 attributes such as DynamicPopOutImageTextFormatString and StaticPopOutImageTextFormatString respectevely for proper implementation rules of section 508. Both of these attributes generate text for image alt attribute. It's quite important moment because menu plays an significant role on a web-page.
Actually I did not find much information about it on Internet. Therefore I decided to post a couple words about it.
