Now default parsers extract the doctype element:

doctype = {
  pos=number, -- when pos parser
  name=string,
  ident=string or nil,
  pubident=string or nil, -- when ident != SYSTEM
  dtd=string or nil,
}

New functions:

• escapeFunctions()
• escapeComment()
• escapeAttribute()
• escapeAttributeAndAmp()
• escapeCDATA()
