The Entrez DTDs have been updated and will be in production tomorrow,
December 14. An outline of the changes is available below.

Thank you.

NLMMedline DTD              
a. Changed entity reference from "nlmmedlinecitation_031101.dtd" to:
"nlmmedlinecitation_041101.dtd"
b. Changed external entity from MedlineID.Ref to NlmDcmsID.Ref

NLMMedlineCitation DTD      
a. Changed entity reference from "nlmsharedcatcit_031101.dtd" to:
"nlmsharedcatcit_041101.dtd" 
b. Added ReprintIn and ReprintOf to CommentsCorrections element.
c. Added values MEDLINE and OLDMEDLINE to the Status internal entity
d. Added attribute PubModel to Article element.  
e. Added PubModel and its values to internal entity List. 
f. Changed element from MedlineID to NlmDcmsID.
g. Removed NCT value from Source internal entity.
**It is possible that we may need to add another valid value for the Source
attribute associated with the OtherID element found in NLMSharedCatCit DTD.


NLMSharedCatCit DTD
a. Changed entity reference from "nlmcommon_031101.dtd" to:
"nlmcommon_041101.dtd" 
b. Added optional Prefix attribute to OtherID element.

NLMCommon DTD
The following changes were made in the nlmcommon_041101.dtd:
a. Deleted JournalIssue attribute of PrintYN.
b. Changed ElectronicPubDate element and its attribute OfficialDateYN to
ArticleDate element and its attribute DateType.
c. Added attribute Valid YN to Author element 

The most substantive changes to the suite of MEDLINE DTDs that affect the
XML distribution are:
1. MEDLINE and OLDMEDLINE records formerly distributed in Completed status
will be distributed in MEDLINE or OLDMEDLINE MedlineCitation status
2. the true spelling of Author names will be indicated through use of the
ValidYN attribute with the Author element (some published author names have
been corrected by the publishers and NLM retains both versions in the
record)
3. the publishers' model of publishing will be indicated through use of  the
new attribute PubModel on the Article element (e.g., Print,
Print-Electronic, Electronic, or Electronic-Print) 
4. the various publishing dates that may be associated with an article will
be indicated through use of the ArticleDate element and its attribute
DateType.
