Via <para> a text paragraph inside <notes> is put into brackets. Starting with version 2.2.0 of UDDF it is always necessary to use <para> when inserting text — even if only one paragraph is needed.
(see also <notes>)
<notes> <para> This is a first paragraph. </para> <para> This is the second paragraph. </para> <link ref="picture_1"/> <para> And this is the third paragraph. Before it via an <link/> element a photo is inserted into the text. </para> </notes>
