<xsd:documentation>Changed all elements that use the langstringType to a multiplicy of 1 or more </xsd:documentation>

<xsd:documentation> 2001-07-25 Schawn Thropp. Updates to bring the XSD up to speed with the W3C </xsd:documentation>
<xsd:documentation> XML Schema Recommendation. The following changes were made: Change the </xsd:documentation>
<xsd:documentation> namespace to reference the 5/2/2001 W3C XML Schema Recommendation,the base </xsd:documentation>
<xsd:documentation> type for the durtimeType, simpleType, was changed from timeDuration to duration. </xsd:documentation>
<xsd:documentation> Any attribute declarations that have use="default" had to change to use="optional" </xsd:documentation>

<xsd:documentation> 2001-09-04 Schawn Thropp </xsd:documentation>
<xsd:documentation> Changed the targetNamespace and namespace of schema to reflect version change </xsd:documentation>
<xsd:documentation> 2001-11-04 Chris Moffatt: </xsd:documentation>
<xsd:documentation> 1. Changes to enable the schema to work with commercial XML Tools </xsd:documentation>
<xsd:documentation> a. Refer to the xml namespace using the "x" abbreviation instead of "xml" </xsd:documentation>
<xsd:documentation> b. Remove unecessary non-deterministic constructs from schema. </xsd:documentation>
<xsd:documentation> i.e. change occurrences of "#any" to "#other" </xsd:documentation>
<xsd:documentation> 2. Revert to original IMS MD version 1.2 namespace. </xsd:documentation>
<xsd:documentation> i.e. "http://www.imsglobal.org/xsd/imsmd_v1p2" </xsd:documentation>
<xsd:documentation> This change done to support the decision to only change the XML namespace with </xsd:documentation>
<xsd:documentation> major revisions of the specification ie. where the information model or binding </xsd:documentation>
<xsd:documentation> changes (as opposed to addressing bugs or omissions). A stable namespace is </xsd:documentation>
<xsd:documentation> necessary to the increasing number of implementors. </xsd:documentation>
<xsd:documentation> 3. Changed name of schema file to "imsmd_v1p2p2.xsd" and </xsd:documentation>
<xsd:documentation> version attribute to "IMS MD 1.2.3" to reflect minor version change </xsd:documentation>
<xsd:documentation> 2005-08-26 Colin Smythe (IMS/GLC) </xsd:documentation>
<xsd:documentation> 1. Added the IMS Copyright statement </xsd:documentation>
<xsd:documentation> 2. Removed the x: prefix references and ensured the import statment uses the W3C </xsd:documentation>
<xsd:documentation> namespace (http://www.w3.org/XML/1998/namespace) and schemalocation </xsd:documentation>
<xsd:documentation> (http://www.w3.org/2001/03/xml.xsd). </xsd:documentation>
<xsd:documentation> 3. Changed name of schema file to "imsmd_v1p2p4.xsd" and made sure the </xsd:documentation>
<xsd:documentation> version attribute to "IMS MD 1.2.4" to reflect minor version change. </xsd:documentation>
<xsd:documentation> 4. The multiplicity of 'taxon' in 'taxon' path has been changed from 0..1 to 0..*. </xsd:documentation>
<xsd:documentation> This problem was identified in the IMS Maintenance Database as issue: 198. </xsd:documentation>
<xsd:documentation> This is now consistent with IEEE LOM. </xsd:documentation>
<xsd:documentation> 5. The recursive element of 'taxon' within 'taxon' has been removed. </xsd:documentation>
<xsd:documentation> This problem was identified in the IMS Maintenance Database as issue: 198. </xsd:documentation>
