    <p>I thought this ought to be simple to find, yet after some searching I found this might be nice to define clearly.</p> <p>In my XSD I've defined an enum, derived from string. In a complex type I've defined and attribute that refers to this enum, with a default value.</p> <p>In my XSL I wish to display the default value of this attribute for elements whose attribute is not explicitly set.</p> <p>The XSD:</p> <pre><code>&lt;xs:complexType name="foo"&gt; &lt;xs:attribute name="bar" type="responsecodes:barType" default="default"/&gt; &lt;/xs:complexType&gt; &lt;xs:simpleType name="barType"&gt; &lt;xs:restriction base="xs:string"&gt; &lt;xs:enumeration value="default"&gt; &lt;xs:annotation&gt; &lt;xs:documentation xml:lang="en-us"&gt;Default bar.&lt;/xs:documentation&gt; &lt;/xs:annotation&gt; &lt;/xs:enumeration&gt; &lt;xs:enumeration value="chocolate"&gt; &lt;xs:annotation&gt; &lt;xs:documentation xml:lang="en-us"&gt;A chocolate ...bar&lt;/xs:documentation&gt; &lt;/xs:annotation&gt; &lt;/xs:enumeration&gt; &lt;/xs:restriction&gt; &lt;/xs:simpleType&gt; </code></pre> <p>The XML:</p> <pre><code>.... &lt;foo/&gt; &lt;foo bar="default"/&gt; &lt;foo bar="chocolate"/&gt; .... </code></pre> <p>I'd expect the XSL to be: (more or less)</p> <pre><code>&lt;ol&gt; &lt;xsl:for-each select="/foo"&gt; &lt;li&gt;BarType: '&lt;xsl:value-of select="@bar" /&gt;'&lt;/li&gt; &lt;/xsl:for-each&gt; &lt;/ol&gt; </code></pre> <p>Now when I display this style XML file, the value of the 'bar' attribute is empty for the non-specified value, while I'd wish to display (or select on) the default value.</p> <p>Now:</p> <ol> <li>BarType: ''</li> <li>BarType: 'default'</li> <li>BarType: 'chocolate'</li> </ol> <p>Desired:</p> <ol> <li>BarType: 'default'</li> <li>BarType: 'default'</li> <li>BarType: 'chocolate'</li> </ol> <p>Now this ought to be quite simple, no?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
