Some thoughs to add to that...

During development of Author/Editor (an SGML editor for those that
don't remember it :-) ), there was a lot of attention spent on how
often it was helpful to offer only valid element and attribute names
for insertion, and how often it was a hindrance.

The result was to make the mode optional, so that you could toggle
between "rules checking" off and on.  You need to turn it off
sometimes, as an edit can make a document temporarily invalid,
or because you might be migrating between two DTDs (schemas these
days maybe) and not have a transitional one in which both sets of
document instances were allowed.

I don't think that means it's never useful to offer a list of
elements that might be valid at the insertion point.  I know I
find it particularly useful for a tightly-structured DTD or schema
with which I have only occasional familiarity.

I wasn't involved in the XMetaL design, which was originally based
on the Author/Editor and HoTMetaL code.

Alan Cooper in his "About Face" suggested that designers of software
should optimsie for the "perpetual intermediate", the person who
doesn't use the software in and out all day.  As long as one does
not take that as advice not to have advanced or powerful features :-),
I think it's good advice.

Best,

Liam
