Wrapper element for a single piece of metadata not otherwise defined in the Tag Suite.
This element can be used as an escape-hatch to record additional metadata that an organization wishes to preserve (so that the intellectual work to capture that content will not be lost) even though there is no direct expression for the metadata in the Tag Set.
The <custom-meta> element allows for an infinite variety of name/value pairs, with few constraints on the length or content of the value. This element will probably be used for special cases, product-specific material, or other unusual metadata, as well as for the special needs of CEN and national bodies.
The following, in order:
... <custom-meta-group> <custom-meta> <meta-name>prev-journal-title</meta-name> <meta-value>Evolution of Biodiversity</meta-value> </custom-meta> </custom-meta-group> ...
