Writers might wish to communicate more complicated formatting that they don't know how to implement themselves. That is fine. This communication should be placed between these two symbols: <!-- and --> . Please make an effort to get these symbols exactly right; we will appreciate that. Examples:
The chemical formula for water is H2O. <!-- the "2" should be a smaller font and subscript, of course -->
<!-- include figure1.jpg here -->
<br><b>Figure 1. A widget.</b></tt>
