# The purpose of this module is provide a common place for logic
|
|
# around Markdown processing.
|
|
#
|
|
# The submodules AllowedTags and AllowedAttributes answer the
|
|
# question: What HTML tags and attributes are allowed for what
|
|
# contexts?
|
|
#
|
|
# In performing some analysis, I found that we had at least 5 places
|
|
# in our code base that specified AllowedTags and AllowedAttributes.
|
|
#
|
|
# There should be parity between the name of constants in both
|
|
# AllowedTags and AllowedAttributes. That is to say if one of those
|
|
# modules has FEED then the other should have FEED as well.
