Most of the program related information is described in well defined sets of allowed phrases, or as numbers. The element programDescriptions, however, provides ample room for descriptive texts.
All textual information can be provided in multiple languages; an optional html version allows for the inclusion of some basic tags (<p>, <br>, <b>, <i>, <ul>, <ol>, <li>, <a>, <h1> and <h2>).
Usually, the text based elements are limited in size. Their html counterparts do not technically force this constraint, but their content should be identical to the text based version.
