Are you using this to hide or display a field? If so, the <?choose"> statement works well for this and the <?when:?> can contain xdoxslt.

xdoxslt and xdofx cannot be mixed.

You might try a combination of <?xdoxslt:specialProcess(xdoxslt:chr('10'))?> to get a Linefeed character, <?xdoxslt:instr('your text','.',1,1)?> to locate the period where you want the insertion to take place and xdofx:replace and substr to generate the final string.

Is the question mark missing in the "otherwise" case in your template? It should be <?otherwise:?>.

Have you tried applying the format on the Word template field properties? This definitely works.
