It supports the following Field types

• T = Text Area
• C = Check Box
• D = Date
• X = Time
• Z = DateTime
• O = Select Box
• M = Multi-Select Box

The fieldname is used as the key for the language resources to translate the field label
OptionsString is a pipe | delimited list of options for radio buttons and select lists.

Nice work.
