Xporter should be able to convert wiki to html

As a user, I should be able to see the wiki styling on an HTML document generated from TXT file.
Furthermore, the Xporter should be prepared for mappings that can be Wiki or Html.
For example:
The add-on JEditor contains the following setting:
Lean formatting: Convert HTML to wiki when possible (use forced mode to ignore 'class' and 'style' attributes)
and the user should be able to use only one function instead of using two mappings in order to know which is correct :

${html:currentField}
${wiki:currentField}
