Some DTDs and schemas allow for metadata above and beyond that which can be specified by this DTD. This element is used to capture metadata elements that have not been defined explicitly in the models for this DTD, so that the intellectual content will not be lost.
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, for example, the journal-history information preserved in at least one publisher’s DTD.
