Re: [xml-dev] Caution! XML parsers behave differently withwhitespace specified directly in attribute value versus whitespacespecified via an ENTITY

There are places where zero-argument macro text substitution is very
helpful. For example, 
  href="&scheme;://&servername;/&docroot;/"
or &productname; in a technical manual for several products.

Having said that, I have yet to see an XML schema language that can
place any constraints on entities. Doing that might require using a
character other than & for entity replacement, or changing XML parsers
to validate the entities as they go.
