		Things to do in costwish and CML
		--------------------------------

In no particular order:

1. SGML output:
	read a list of EMPTY tags and check against the GI being output
	Otherwise it works?
	Needs filebrowser for output (at present to stdout!!)

2. HTML output:
	requires formatting routine for native HTML tags
	translation table for other DTD tags (e.g. X.AUT for author)
	these will go in xml.tcl, etc.

3. Node selection:
	This is just a placeholder at present.  I intend that any node or
	group can be selected and used for display, output, etc.
	The selection mechanism works but nothing is done

4. Attributes and contents.  This is a horrid display at present and needs
	a lot of hacking.  There needs to be an 'undo' button for every
	widget.  Sometimes multiple boxes come up.

5. Tables (X.LIST TABLE).  Not written (uses generic display at present).  I'd
	also like to use BLT to plot two or more numeric arrays

6. Tree pruning.  Depth option required, also 'select with attribute/value'
	to map onto COST.  

7. DTD management.  Load in DTDs via menu rather than hardcoding.  Also
	allow for more customisation via files.

8. LaTeX (and postscript) output.  The bits are there but messy and not 
	bolted in.

9. Help should use a hypertext widget?

10. Make external hypertext links work from HIPPO?
