How to make part of the report text field bold

Requirement:

Making part of the report text bold without using separate text fields.

Resolution:

User can use styled markup to set report field text element, then us style property to wrap around the text to make it bold.

<textField>
    <reportElement key="" x="0" y="0" width="570" height="30"/>
    <textElement markup="styled"/>
    <textFieldExpression>
        <![CDATA["<style isBold='true'>"+" Who: " + "</style>" + "Who"]]>
    </textFieldExpression>
</textField>

Here is the sample report template to demonstrate the approach:
