Corrected last validation error

The ul-tag is not allowed inside the p-tag. The specification[0]
states that the p tag can contain only phrasing-elements[1]:

  a em strong small mark abbr dfn i b s u code var samp kbd sup sub q
  cite span bdo bdi br wbr ins del img embed object iframe map area
  script noscript ruby video audio input textarea select button label
  output datalist keygen progress command canvas time meter
