<para>
In order to use the XML Data Access Service for Service Data Objects,
you will need to understand some of the concepts behind SDO:
the data graph, the data object, XPath and property expressions,
and so on.
If you are not familiar with these ideas, you might want to look first at
<link linkend='ref.sdo'>the section on SDO</link>.
</para>
<para>
The job of the XML DAS is to move data between the
application and an XML data source, which can be either a file or
a URL. SDOs are always created and maintained according to a model
which defines type names and what property names each type may have.
For data which is from XML, this SDO model is built from a schema file
written in XML schema language (an xsd file). This schema file is
usually passed to the create method when the XMLDAS is initialised.
The
<link xlink:href='&url.ibm.sdo;'>SDO 2.0 specification</link>
defines the mapping between XML types and SDO types.
There are a number of small limitations in the PHP support -
not everything which is in the specification can be done - and
these limitations are summarised in a later section.
