XML Primer – Schema Example

<xs:element name="illness" maxOccurs="unbounded">  <xs:complexType>    <xs:sequence>      <xs:element name="title" type="xs:string" />      <xs:element name="code" type="xs:decimal" minOccurs="0" />      <xs:element name=“dateonset" type="xs:date" />    </xs:sequence>  </xs:complexType></xs:element>

• X12 Implementation Guide Concepts– Loops Segments Elements– Repeats– Constraints– Delimiters

XML and X12

• X12 278 – Loop 2010A – UMO Name– Loop element name defined (xs:element name) and name

description (xs:documentation)

X12 XML Schema Example

• X12 278 – Loop 2010A – UMO Name– Allowable/expected segments are indicated in nested tags

(xs:element ref)

X12 XML Schema Example

• X12 278 – Loop 2010A – UMO Name– Number of segment occurrences is described by attributes (xs:element

minOccurs maxOccurs)– Segments appear as child elements and are defined further down the

XSD document
