Actually, it appears that the World Wide Web Consortium has taken the issue on
board and included two mechanisms for text transclusion in the new HTML 4.0
working draft (previously codenamed "Cougar"). See http://www.w3.org/MarkUp/
The <OBJECT> tag. From the HTML 4.0 working draft:

This leads us to Method 2, based on the <IFRAME> Netscape extension tag
introduced in Netscape Communicator 4.0:

Microsoft has announced that HTML 4.0 will be supported starting with
Microsoft Internet Explorer 4.0 Preview 2, available this month, and
Netscape has announced support in a future release of Communicator.
I note also that the HTML 4.0 working draft finally adds support for
bi-directional and external links!
