[Utilities-announce] Changed Entrez DTDs

[utilities-announce-admin at ncbi.nlm.nih.gov]

The NCBI Entrez Utilities will soon conform to updated DTDs available at:

http://www.ncbi.nlm.nih.gov/entrez/query/DTD/index.html

At the end of each year NLM maintains the MEDLINE citations in PubMed. 
During this process data fields may be added, eliminated, or changed. As a 
result of the year end processing the DTDs may also be modified. Please 
consult the Corrections, and Revision Notes Sections of each DTD for 
details on these changes.

We anticipate switching to the updated DTDs in late November or early 
December. Another message will be posted on this listserv when we have a 
definitive date.
