The MiningStructure XSD depends upon element definitions in namespaces other than the default namespace. The following elements are defined in the namespace eng100_100:

   <xsd:element name="HoldoutMaxPercent" type="xsd:int" />
   <xsd:element name="HoldoutMaxCases" type="xsd:int" />
   <xsd:element name="HoldoutSeed" type="xsd:int" />
   <xsd:element name="HoldoutActualSize" type="xsd:int" />

The following table describes the elements that are included in the XSD schema for MiningStructure. Those elements common to all major objects are described in section 2.2.4.2.2.1.

Element	Read-Only	Default value	Description
Source		Empty	The source for the MiningStructure data. Source is of type "Binding". One of the following derived classes MUST be used: DataSourceViewBinding, DimensionBinding, or CubeDimensionBinding. If DimensionBinding or CubeDimensionBinding is used, then the DataSourceID for DimensionBinding and CubeDimensionBinding MUST indicate an OLAP source.
LastProcessed	Yes		The date and time when the mining structure was last processed.
Translations		Empty	A collection of Translation objects.
Language		Empty	The LCID of the language to use by default. See [MS-LCID] for information about LCIDs. If empty, the server will determine the language to use.<92>
Collation		Empty	The collation of this MiningStructure.
ErrorConfiguration		Empty	Error configuration settings to deal with issues in the source data.
CacheMode		"KeepTrainingCases"	Determines caching mechanism for training data retrieved during mining structure processing.
HoldoutMaxPercent		Zero	An integer value between 0 and 99 that specifies the maximum percentage of the cases that are to be held out as the test set. The remaining cases become the training data set. Zero indicates no limit.
HoldoutMaxCases		Zero	An integer value equal to or greater than zero that specifies the maximum number of cases that are to be held out as the test set. The remaining cases become the training data set. Zero indicates no limit. If not zero, then the lowest of (HoldoutMaxCases, HoldoutMaxPercent) is used.
HoldoutSeed		Zero	Used as the seed for repeatable partitioning. If unspecified or set to zero, a hash of the mining structure name is used as the seed.
HoldoutActualSize	Yes		If the mining structure is processed, this indicates the actual size of the test data set, expressed in number of cases. Zero indicates either no test partition or that the structure is not processed.
Columns		[Required]	A collection of Column objects of type MiningStructureColumn.
State	Yes		The state of processing of the object.
MiningStructurePermissions		Empty	A collection of MiningStructurePermission objects. Each MiningStructurePermission defines the permissions a role has on this MiningStructure.
MiningModels		Empty	A collection of MiningModel objects.
