Hmmm
It seems that Xara will not forget the last "image" generated when the box is unchecked.
Note also that the position of the tag within the code is dependant on its position in the layer structure. Sending it to the back will place it at the top of the code.
Google, and probably other search engines, see little difference between <h1> tags and large bold text. They are, so I gather, useful to people using some screen readers.
Improved version attached.
