STX improvements to the DTML Reference. Also slightly improved the documentation of dtml-var entity syntax (again).

Simplify the path math used to make sure we can pick up unittest.

The module from Python was sgmllib, not nsgmllib.

(Should we still include the standard Zope license?)

are (still) not sequences.

Added standard main test functions and function-choosing script
handler.

Test for the HTMLTALParser code generator.

Add tests for some boundary conditions, including buffering artefacts.

._run_check():  Add support for passing the data in as a list of strings,
    to support simulating buffer boundaries.

Make the two headers in the summary (commented out) symmetric.

Re-wrote parsing of attributes to be more robust and detect
substantial errors more reliably.  (Now works even if "<" or ">"
occurs in an attribute value!)

Added documentation of the url attribute and how to use attributes with the entity syntax. Also clarified use of the fmt attribute.

finish_starttag():  Make sure we do not close too many levels; this was
    possible with some interactions between nested tables.

Merged in Jim's big fix from 2.3 branch dealing with returning the lexicon attributes of a Vocabulary object.

Test cases for TAL.HTMLParser module.

Add some helper functions for use in test cases.

Rename nsgmllib to HTMLParser; there really is not any SGML capability
beyond the HTML support at this point.  Rename all references.

New catalogs have 'lexicon' attributes that are lexicon names, but
old catalogs store their lexicons directly. This makes it hard
to manage text indexes correctly. Added some code to assure that
when a text index is added, we always pass the actual lexicon.

When converting BTrees, convert indexes in context. This is necessary
to help UnTextIndexes get their (previously) acquired lexicons.

UnTextIndexes now refer directly to their lexicons.

Added logic in conversion code to implement the rule above.

Took out some broken code to unscrew some hysterical breakage.

some old broken lexicon settings.

would trigger the error "replace structure with attribute replacements
not yet implemented".  We were right that it needed testing --
TALError was not imported.

Fixing this in TALInterpreter.py, and adding code to TALGenerator.py
that passes the "repldict" variable from emitStartElement() to
emitEndElement(), through the "todo" variable, when a "replace"
command is present.

hence were unable to cope with the newlines that may occur in HTML
attributes.  This caused sustitution of "str:foo\nbar" to insert
"foo", omitting "\nbar".

None (for auto), use a variable mode which can be "html", "xml" or
None.

METALError exception (and slight rewording of message).  (This was
Tim's idea.)

mixed with old.

Need to copy length value to __len__.
