nop, humm did you try to use the AbstractObservationType factory, change the type, and set the result *content* (ie boolean) instead of setting the full tree ? I suspect that it may be a bug/feature of set to not add extra typing attributes while using set(XmlObject) sorry jc ><complexType name="ObservationType"> > <annotation> > <documentation>Observation event. > carries a generic "result" properties of type >"anyType".</documentation> > </annotation> > <complexContent> > <extension base="om:AbstractObservationType"> > <sequence> > <element name="result" type="anyType" nillable="true"> > <annotation> > <documentation>an xsi:type attribute may appear >in the instance to indicate the type of the result</documentation> > </annotation> > </element> > </sequence> > </extension> > </complexContent> > </complexType> ><complexType name="AbstractObservationType"> > <annotation> > <documentation>Base type for Observations. > > Concrete Observation types must extend this type with a >"result" of the appropriate type. > > The following properties are inherited from EventType: > <!-- from AbstractGMLType > <group ref="gml:StandardObjectProperties"/> --> > <!-- or > <element ref="gml:metaDataProperty" minOccurs="0" >maxOccurs="unbounded"/> > <element ref="gml:description" minOccurs="0"/> > <element ref="gml:name" minOccurs="0" >maxOccurs="unbounded"/> --> > <!-- from AbstractFeatureType > <element ref="gml:boundedBy" minOccurs="0"/> --> > <!-- from EventType > <element name="eventTime" type="om:TimeObjectPropertyType" >nillable="true"/> > <element name="eventLocation" >type="om:LocationPropertyType" nillable="true"/> > <element name="precedingEvent" type="gml:StringOrRefType" >minOccurs="0" maxOccurs="unbounded"/> > <element name="followingEvent" type="gml:StringOrRefType" >minOccurs="0" maxOccurs="unbounded"/> > <element name="responsible" type="meta:PartyPropertyType" >minOccurs="0" maxOccurs="unbounded"/> --> > > </documentation> > </annotation> > <complexContent> > <extension base="om:EventType"> > <sequence> > <element name="procedure" >type="om:AbstractSensorSystemPropertyType"/> > <element name="observedProperty" >type="swe:PhenomenonDefinitionPropertyType"> > <annotation> > <documentation>Link to a description of the >property or phenomenon whose value is being described or estimated through >observation > for example "wavelength", "grass-species", >"power", "intensity in the waveband x-y", etc. > It is this feature-property that provides the >(semantic) type of the observation. > Note that the description of the phenomenon may >be quite specific and constrained. > In general the precise details of the >constraints describing the observe properties require attention to the >procedure used in making the observation: > e.g. an optical sensor typically has a >wavelength-dependent response. > This property may be provided for client >convenience, to allow comparison between and aggregation of observations of >the same property made using different procedures.</documentation> > </annotation> > </element> > <element name="quality" type="meta:QualityPropertyType" >minOccurs="0" maxOccurs="unbounded"> > <annotation> > <documentation>Allow multiple quality measures >if required.</documentation> > </annotation> > </element> > <element name="target" type="gml:FeaturePropertyType"> > <annotation> > <documentation>the Feature or location >regarding which the observations are being made, > sometimes called the subject of the observation, such as a >specimen, station, tract, mountain, pixel, etc.</documentation> > </annotation> > </element> > <!-- > <element name="result" type="anyType"> > <annotation> > <documentation>This is a placeholder - concrete >types must replace (restrict) this with a "result" property of the correct >type. </documentation> > </annotation> > </element> > --> > </sequence> > </extension> > </complexContent> > </complexType> > > >Thank you for any other help you can offer. > >Doug > > >On 8/18/05 5:15 AM, "Jean-Christophe Pazzaglia" ><[EMAIL PROTECTED]> wrote: > > > >>well, >> >>as far as I understood, >>the xsi:type usually appears when the type is not stricly defined >>(for example to enable subtyping of elements), I suspect that your >>schema is too strict.
