A Gtk.TextView-based renderer for XHTML-IM, as described in:

http://xmpp.org/extensions/xep-0071.html

Starting with the version posted by Gustavo Carneiro,

I (Santiago Gala) am trying to make it more compatible

with the markup that docutils generate, and also more

modular.

# This Integration Set includes a subset of the modules defined for
|
|
# XHTML 1.0 but does not redefine any existing modules, nor
|
|
# does it define any new modules. Specifically, it includes the
|
|
# following modules only:
|
|
#
|
|
# - Structure
|
|
# - Text
|
|
#
|
|
# * Block
|
|
#
|
|
# phrasal
|
|
# addr, blockquote, pre
|
|
# Struc
|
|
# div,p
|
|
# Heading

|
# h1, h2, h3, h4, h5, h6

# - List (ul, ol, dl)

# - Image (img)
|
|
# - Style Attribute
|
|

|
|

|
|
#
|
|
# Block.mix
|
|
# Block-like elements, e.g., paragraphs
|
|
# Flow.mix
|
|
# Any block or inline elements
|
|
# Inline.mix
|
|
# Character-level elements
|

# InlineNoAnchor.class

# Anchor element
|
|
# InlinePre.mix
|

# Pre element

# Core.extra.attrib
