The <text:conditional-text> displays one text string or another 
depending on a condition.

 but the content model says:

The content of the element contains the displayed text at the time of 
saving, so that consumers, which does not support this text field or do 
not support the language of the condition, can at least show the current 
content of this field.

Similar with the attribute text:current-value. It contains the result of 
the evaluation of the text:condition element. It ease an initial display 
or a transformation to a different format without evaluating the 
condition once again. Evaluating the condition might be costly (e.g. 
complex query of databases) or not possible in current situation (e.g. 
working on a document on a smart phone).

If the condition is evaluated again, the content of the 
<text:conditional-text> element and the value of the text:current-value 
attribute is updated.

No, the content is needed, see above.
