Is it possible to have a variable as value in Jasper XML - jasper-reports

Question

I want to make a table with dynamic headers for a PDF in Grails using Jasper. One of the possible solutions would be to have a property as a value for an xml attribute. I have a hard time explaining it in English,so maybe it's better to leave an example, here is the xml code for a static header in a table:
<staticText>
<reportElement x="29" y="183" width="118" height="32"/>
<box>
<pen lineWidth="1.0"/>
<topPen lineWidth="1.0"/>
<leftPen lineWidth="1.0"/>
<bottomPen lineWidth="1.0"/>
<rightPen lineWidth="1.0"/>
</box>
<textElement textAlignment="Center">
<font isBold="true"/>
</textElement>
<text><![CDATA[Column header text]]></text>
</staticText>
What I want to know is, is it possible to have a parameter for the value of x, y and every other attribute value for the element, like for an example this:
<staticText>
<reportElement x="<![CDATA[$P{columnX}]]>" y="<![CDATA[$P{columnY}]]>" width="<![CDATA[$P{columnWidth}]]>" height=32/>
<box>
<pen lineWidth="1.0"/>
<topPen lineWidth="1.0"/>
<leftPen lineWidth="1.0"/>
<bottomPen lineWidth="1.0"/>
<rightPen lineWidth="1.0"/>
</box>
<textElement textAlignment="Center">
<font isBold="true"/>
</textElement>
<text><![CDATA[Column header text]]></text>
</staticText>
The parameter would be declared like this:
<parameter name="columnX" class="java.lang.Long"/>
