Unclear what: "For interoperability, authors are advised to avoid optional features of XML" means.

Can this be changed to something more along the lines of:
According to the XML specification, XML processors are not guaranteed to 
process the external DTD subset referenced in the DOCTYPE. This means, 
for example, that using named character entities for characters in XHTML 
documents is unsafe (except for <, >, &, " and '). 
When using XHTML, it is recommended that authors use the UTF-8 charset. 
Additionally, authors can use numerical or hexadecimal entities, for 
example use the numerical reference ™ to display the trademark symbol.

> For interoperability, authors are advised to avoid optional features 
> of XML.

It's unclear to me what this sentence is actually trying to say here. 
This could mean a lot of things.
Perhaps one of the editors could explain what the reader is supposed to 
take from this sentence.
