Hello WG2,

The schema modification for the approved by WGII ( < has been implemented and is ready for technical review.

Reinoud, I suggest a two week deadline for this review.

The Github pull request is here:

A direct view of the changes is here:

Modifications from the original proposal are as follows:

1) Remove prefix from Identifier value as requested by the authors of the proposal.
2) Fixed IdentifierElement => IdentifierType so consistent with example and other schema types.
3) Added an annotation to IdentifierType to describe usage:
<xs:documentation>A type to document persistent identifiers.
Identifier values should be specified without a URI scheme (prefix),
instead the identifer type is documented as an attribute.
4) Added maxOccurs="unbounded" to the usage in BaseNodeType to allow more than one Identifier:
<xs:element name="Identifier" type="fsx:IdentifierType" minOccurs="0" maxOccurs="unbounded"/>
