These are what you want. In the case of tokens, it will separate each word
into a list element. A "lines" property separates each line into a list
element.

Tokens: 'foo bar baz' = ['foo', 'bar', 'baz']
Lines:
foo bar
bar
baz

Becomes: ['foo bar', 'bar', 'baz']

This should work fine using standard <dtml-in>s, since tokens and lines are
sequences.
