It makes no sense to adopt a one-size-fits-all approach to filtersets: therefore, users must be able to define their own sets of allowed elements, as well as switch in-between doctypes of HTML.

Our goals (pending reorganization):

• Easily switch from one doctype to another,
• Create own doctype, possibly non-HTML based,
• Select a custom set of tags and attributes,
• Select XHTML 1.1 style modules,
• Switch on/off dangerous tags,
• Define custom behavior for pre-existing tags,
• Define custom tags for their own use,
• Define custom attribute type / override existing one,
• Change the root node which fragment will be inserted in.
