I am using FOP 0.20.2. I am having a problem while applying 'text-decoration' and 'vertical-align' attributes to a nested fo:inline. I have some text content in the inner fo:inline where the effect of the above attributes is not being seen, when they are specified in the outer fo:inline. If content is in the fo:inline where the attributes are specified, things are working fine.
The XSL spec says that both text-decoration and vertical-align are not inherited (http://www.w3.org/TR/xsl/slice7.html#vertical-align).
So FOP just sticks to the rules...
