Please note... The list represents a tree because each node is:

I missed that ... I didn't look too closely at your representation. Effectively, this means that a simple list traversal corresponds to a depth-first left-to-right of the tree, right? I'd say it's still less easy (through clearly possible) for an application to adopt alternative traversal patterns.

I am not sure what the representation you just gave is???

[[ element ]]

surely that simplifies to a list of elements... what am I missing?

? I just quoted some declarations from HaXml. The types Element and Content there are mutually recursive, providing the basic tree structure. I don't see where [[ element ]] comes from. #g ------------ Graham Klyne For email: http://www.ninebynine.org/#Contact
