    Introduction
      This schema defines the DICOM standard data types that are used 
      by all other DICOM XML schema definitions.
      
    Naming conventions:
    All DICOM value representation (VR) types are named with a 
    2-character string, such as "AE" and "CS".
    All DICOM attribute type definitions are named as VR_ATTR_T, 
    where VR is replaced by the attribute's 2-character VR.
    
    Note that each item of a sequence type (SQ) is of DATASET_T type.
    The DATASET_T type can recursively contain more attributes.
    The element name of an attribute is its value representation (VR)
    name. Oracle uses value representation names defined
    by the DICOM standard part 5. The element
    name to VR mappings are:
      APPLICATION_ENTITY     ---   AE
      AGE_STRING     ---  AS
      ATTRIBUTE_TAG     ---  AT
      CODE_STRING     ---  CS
      DATE     ---  DA
      DECIMAL_STRING     ---  DS
      FLOAT_SINGLE     ---  FL
      FLOAT_DOUBLE     ---  FD
      INTEGER_STRING     ---  IS
      LONG_STRING     ---  LO
      LONG_TEXT     ---  LT
      OTHER_BYTE     ---  OB
      OTHER_FLOAT     ---  OF
      OTHER_WORD     ---  OW
      OTHER_WORD     ---  OWB
      PERSON_NAME     ---  PN
      SHORT_STRING     ---  SH
      SIGNED_LONG     ---  SL
      SEQUENCE     ---  SQ
      SIGNED_SHORT     ---  SS
      SHORT_TEXT     ---  ST
      TIME     ---  TM
      UNIQUE_ID     ---  UI
      UNSIGNED_LONG     ---  UL
      UNKNOWN     ---  UN
      UNSIGNED_SHORT     ---  US
      SIGNED_SHORT       ---  USS
      UNLIMITED_TEXT     ---  UT
      EXTENDED_TYPE     ---  EXT
      EXCEPTION_TYPE     ---  EXP
      The VR types "OWB', "EXT", "EXP" and "USS" are 
      Oracle-defined extensions.
      Please refer to the individual data type documentation for 
      more explanation.

      <xs:documentation>DICOM Value representation Age String. 
        The age string can be expressed either in DICOM string 
        format, or in number of days. When metadata is extracted 
        from a DICOM object, both elements will be populated.
        XML documents can represent age by either format.  
        Age in number of days is converted into an age string when 
        XML metadata is encoded into a DICOM object.
        To convert from age string into the number of days:  
          365 * number_of_year or 31 * number_of_month.  
        Because AGE_STRING is mandatory, it is not necessary to 
        convert from the number of days into an age string.

        attribute types.
        The "tag" attribute defines DICOM attributes in little-endian encoding.
        The "definer" attribute specifies the organization that has
        created the attribute. By default, all DICOM standard 
        attributes have the definer name "DICOM".
        The "name" attribute specifies the canonical attribute name
        as defined by the data dictionary. For example, in 
        an XML metadata schema definition, you can choose a tag
        PATIENT_DATE_OF_BIRTH or "DOB" for DICOM attribute 
        (0010,0030), but its name attribute should match that of the
        DICOM standard: "Patient's Birth Date".
        The "number" attribute is an optional attribute to indicate the
        ordering of a multivalued attributes.  Number counts from 1 up.
        The "truncated" attribute takes a Boolean value. If it is true,
        it indicates that the original length of the DICOM attribute
        exceeds the maximum length allowed for this XML value;therefore,
        it is truncated in XML. When this attribute is true, 
        xsi:nill="true" for this attribute.
        Optionally, the "rawValue" attribute can be used to store 
        values that do not conform to the DICOM standard.   The 
        associated attribute "byteOrderLE" specifies the byte order
        of the byte stream for the "rawValue" attribute.
        "offset" and "length" are Oracle-reserved attributes.

        attribute definer, which can be the DICOM standard
        (DICOM) or other private sources. 
        A locator path can also identify a particular

        The n-th item of a sequence attribute is denoted by
        "xxxxxxxxx(definer)[n]".

        The index "n" of an item address "[n]" must be a 
        positive integer. The item address suffix can be 
        omitted if the item it pointed to is the first item

        DICOM value representation types.
        In the DICOM standard, VR for certain attributes 
        is defined as "other word or byte", "US or SS", or
        "See Note". Oracle has extended the list of VR types and 
        introduced OWB (for "other word or byte"), 
        USS (for "US or SS"), and 
        EXP (where VR definition does not apply).
        When an attribute of USS type is encoded into XML, it is
        automatically encoded as a signed short type.
        When an attribute of OWB type is encoded into XML, it is
        automatically encoded into other word type.
        An example of an attribute with VR type of EXP is
        the sequence item (FFFE, E000).
        For compatibility with future DICOM releases, if a new 
        DICOM VR is introduced by the DICOM standard, 
        users can mark such attributes as type "EXT??", 
        where "??" should be replaced by the new VR name.
