Short syntax equivalent

What’s the difference between

        <Crop CropVisible="No"></Crop>

and

        <Crop CropVisible="No"/>

Are both valid?

What is the technical name for this construct?

Notepad++ changes the top one into the bottom one when I reformat.

>Solution :

There is no difference. They are both valid. It is an empty element tag (colloquially known as a self-closing tag) as opposed to a start tag and an end tag.
