06/12/02 Created new attribute TYPE on element ISSN. Possible values are "electronic" and "print". Made ISSN 'one or
more'
within PUBFM, PARENT and PUBINFO. Changes were made to support "dual issn's" - print and electronic - currently being used for the Reviews and eventually the Research titles and Nature.
05/29/02 All default attribute values were quoted as per XML requirements.
XML does not support tag minimizations (Unclosed start-tags, Unclosed end-tags etc.) All instances of "- -" "- o" "o o" "o -" were removed.
XML does not support NUMBER(S), NUTOKEN, CDATAS and NAME type attribute values. These were all replaced with CDATA.
XML does not support SDATA entitities. SDATA removed from Nataminc SGML Entities
XML does not support inline comments within an entity declaration. Inline comments were placed outside in external comments.
XML does not support Exclusion models. E.g. In the CalsTbl.dtd: <!ELEMENT table (%tabl;) -(table) >. All Exclusions were removed.
Processing instruction <?SDATRANS> was removed as XML requires default attributes to be a literal value.
XML does not allow spaces within attribute values as within the SDAFORM, SDARULE, SDAPREF, SDASUFF, SDASUSP attributes in ISO Math dtd. Any spaces were removed. Commented out definitions and uses of SDAFORM, SDARULE, SDAPREF, SDASUFF, SDASUSP as they are not used for NPG
XML imposes rules on Mixed Content Models. #PCDATA must occur first in list of unordered elements. Revised mixed content models accordingly.
XML syntax for defining parameter entities for elements cannot contain parenthesis. Parenthesis removed.
