Circular definitions

A circular definitions occur in documents if a value of variable is dependent on its own value. These definitions can occur in global variables and other more advanced XSLT constructs, but not in local variables. In local variables we would get different error - variable not declared - if we try to achieve circularity.

XSLT

                        omit-xml-declaration="yes"/>
            <xsl:variable  name="xxx"
                        select="$yyy + 5"/>
            <xsl:variable  name="yyy"
                        select="$zzz + 5"/>
            <xsl:variable  name="zzz"
                        select="$xxx + 5"/>

            <xsl:template  match="/aaa">
                  <xsl:value-of  select="$xxx"/>
            </xsl:template>

      </xsl:stylesheet>
