In such situations, I keep an instance for logging messages, that can be  
saved and/or viewed as and when necessary.

<instance id="log">
    <log xmlns="">
       <message/>
    </log>
</instance>

<action ev:event="xforms-link-error">
    <insert ref="instance('log')/message"/>
    <setvalue ref="instance('log')/message[last()]">ERROR:  
xforms-link-error !</setvalue>
</action>

Or:

<instance id="log">
    <log xmlns="">
       <message level="" time=""/>
    </log>
</instance>

<action ev:event="xforms-link-error">
    <insert ref="instance('log')/message"/>
    <setvalue  
ref="instance('log')/message[last()]">xforms-link-error</setvalue>
    <setvalue ref="instance('log')/message[last()]/@level">error</setvalue>
    <setvalue ref="instance('log')/message[last()]/@time" value="now()"/>
</action>
