Comprices information about one step of a task that has to be divided into several substeps.
A sequence item (or rather the element <steg>) can contain other sequences on a lower level <sekvens.sub>.
Warning <varn> and caution <obs> concerning the entire sub-sequence are entered as the first part of the sub-sequence. Notes <anm>, tables <tabell>, and graphics <bild> that also concern the entire sub-sequence are entered as the last part of the sub-sequence. If they concern only one or several but not all steps in a sequence, those steps are placed in a <sekv.block.sub>.
References to an entire sub-sequence are made to this element.
