Javadoc
The type of the base of a link.
The local tagname of the referenced element (e.g. 'molecule' or 'peakGroup'). This acts as a partial check on the integrity of the link. Software can assume that the referenced element is of a given tytpe and can create an object supporting that type.
This attribute can be attached to the 'map' attribute and requires all contained links to be of this type. This can be overridden by a 'toType' attribute on indivdual links, but it may also be useful to split the map into maps od different link types.
