When using self-hosted WordPress, you have the option of writing in "Visual" or "Text" mode.
Assuming there's no plugins installed,
Is this "Text" format a well defined standard or pseudo standard? (like markdown, textile, etc.)
Is there a single place in a plugin-less
3.5.1WordPress where this text is converted into HTML?
If the answer to number 2 is "No", how is this text converted into html?
