Hello scala-xml -- I did not mean to exclude any xml specialists from
this discussion, quite the contrary. There is a current thread on
scala-internals begun by the message below, which so far is coming down
heavily on the side of altering the relationship. If any XML experts
would like to weigh in, now would be a good time. (Either on the
internals list or here, I can forward input if you aren't inclined to
join internals yourself.)

The Road To Hell Resurfacing project is going very well. I don't want to
make any excuses beyond saying it's been a tough most-of-a-year.

To be frank, the inheritance relationship under present discussion has
been one of the heavier straws on the back of every sickly, stunted
metaph^Wcamel of motivation I've managed to bring into the world during
the too-few and too-brief syzygies of spare time and excess brainpower
I've in been able to focus on the Scala XML project.

Enough overwrought metaphors; I can't promise any significant coding
effort in the next few months but I'll certainly engage with the
discussion and be of whatever help I can.

To the present point, I definitely agree that the inheritance
relationship has to be removed or replaced with something much less
confusing. It would be very good to hit the 2.8 launch window.

Does this also entail to remove NodeSeq (and move the methods to Node)? What about attribute values then?

Re: (fwd) the mayor of xmltown

Hi, my feeling is that first of all the scala-xml group should develop a paper
which summaries their 'big picture' and the actual state of development. It
should give answers to basic questions like:

- What do we need?
- Features of core Scala language: XML literal, construction, well
formedness, navigation, pattern matching, …
- Used features of JRE/.NET environment: SAX parsing, ...
- Pure xml 1.1 support (http://www.w3.org/TR/xml11) not met by above items:
element, attribute, comment, processing instruction, CDATA,
internal/external entities, ...
- Namespace support (http://www.w3.org/TR/xml-names)
- push and pull parsing, DOM
- validation against definitions expressed in DTD, XML schema, Relax NG,
schematron, ...
- data types and data binding according to above definitions (analog JAXB)
- XPath support
- XQuery support
- XSLT support

- How to implement those features (in core language, in packages, as wrapper
for existing jars or .NET solutions , …)?

- Problems with actual implementation state? Especially:
- Class hierarchy
- Pattern matching
- Known bugs (1787, 2326, ...)

- Should we continue projects - what is their
priority (http://lamp.epfl.ch/~emir/projects/):
- schema2src
- xslt2src
- xquery2src
- xinc
- ...
