<tc:tab label="Only label"/>
A label and an image is set.
<tc:tab label="Label with image" image="#{request.contextPath}/image/feather-leaf.png">
A label and an image is set to an bootstrap icon.
<tc:tab label="Label with icon" image="bi-gender-female">

<tc:tab image="#{request.contextPath}/image/feather-leaf.png">

<tc:tab image="bi-gender-male">
Neither a label or an image are set. In this case the header gets a label with the indexnumber of the tab in
the tabgroup.
It's also possible to set the label via a label facet. So you can use e. g. converters.
If using this, don't forget to set
labelLayout="skip" plain="true" to switch off
the layout and boxes of the components.
