What to call a variable that is used for indentation?
c#
I think it's fine.  As long as it's descriptive to someone coming after you to follow.  I usually try to follow a .NET class if I know they have something similar.  In this case I would have followed the xmlwriter class IndentChars property.  But it's quibbling over little things and not worth investing too much time once you have a name that is clear.
