DefineTextformat (without alignment) overrides td alignment

[Demostenus]

Hello,

I noticed a strange behaviour:
If I define a text format without alignment, and I am interested only in other attributes, ex: hyphenate.
The text format will have a default alignment that overrides any other coming from a parent element.

Below you can see an example I modified to illustrate this.

I define the textformat like this:

<DefineTextformat name="nohyphen" hyphenate="no"/>

I use it here:
<Td align="center" border-right="1pt" border-right-color="white"><Paragraph textformat="nohyphen"><Value select="$classname"></Value></Paragraph></Td>

So my expectation here was the text to be center aligned because it has Td align="center" and the textformat applied does not mention any alignment.
But it doesn't work, the text is either left aligned or justified (default for DefineTextformat)?

data.xml
layout.xml

I think your expectation is "correct" or sensible, but I doubt that I can change the behaviour without breaking older layouts. When defining a text format, justified is always the default (and set). I could make a flag "user has provided an alignment setting", and consider this in the table cell, but this would lead to incompatible layouts (so I assume)
