James:
The sub-text is that someday we may want to allow types to be derived from
other types by a variety of operations. Add-at-the-end would be one of
them
but we may want to allow others such as add-at-start, reorder-contents,
etc.
To leave the door open for the syntax specifies both the source type and
the
operation that creates the new type.
Having said that, I would prefer that
derivedBy="extension"
be replaced by
derivedBy="appending"
All the best, Ashok

Subject: concrete syntax for derivation
I find the current syntax for derivation
<type name="extendedName" source="personName" derivedBy="extension">
highly cumbersome and unintuitive. Why not the obvious and much simpler
syntax of
<type name="extendedName" extends="personName">
?
