The Normative version of the XML Schema for the Native DICOM Model follows:



start = element NativeDicomModel { DicomDataSet }

# A DICOM Data Set is as defined in PS3.5. It does not appear
# as an XML Element, since it does not appear in the binary encoded
# DICOM objects. It exists here merely as a documentation aid.

DicomDataSet = DicomAttribute*
DicomAttribute = element DicomAttribute {
Tag, VR, Keyword?, PrivateCreator?,
( BulkData | Value+ | Item+ | PersonName+ )?
}

BulkData = element BulkData{ UUID }
Value = element Value { Number, xsd:string }
Item = element Item { Number, DicomDataSet }
PersonName = element PersonName {
Number,
element SingleByte { NameComponents }?,
element Ideographic { NameComponents }?,
element Phonetic
{ NameComponents }?
}

NameComponents =
element FamilyName {xsd:string}?,
element GivenName {xsd:string}?,
element MiddleName {xsd:string}?,
element NamePrefix {xsd:string}?,
element NameSuffix {xsd:string}?

# keyword is the attribute tag from PS3.6
# (derived from the DICOM Attribute's name)
Keyword = attribute keyword { xsd:token }
# canonical XML definition of Hex, with lowercase letters disallowed
Tag = attribute tag { xsd:string{ minLength="8" maxLength="8" pattern="[0-9A-F]{8}" } }
VR = attribute vr { "AE" | "AS" | "AT"| "CS" | "DA" | "DS" | "DT" | "FL" | "FD"
| "IS" | "LO" | "LT" | "OB" | "OF" | "OW" | "PN" | "SH" | "SL"
| "SQ" | "SS" | "ST" | "TM" | "UI" | "UL" | "UN" | "US" | "UT" }
PrivateCreator = attribute privateCreator{ xsd:string }
