Question on field type "definition" set to "longtext"

[heidivanparys]

What is the reason behind setting the field type of the field definition to `longtext´?

When adding an item via the GUI, for an item class using the field definition, this gives the following (note the <p> tags):

    "definition" : {
      "text" : "<p>item 1</p>",
      "lang" : "da"
    },
    "id" : {
      "text" : "1",
      "lang" : "da"
    },
