How to implement tgroup/@align attribute in PDF output?

[Toshihiko Makita]

I've been developing PDF plugin for DITA Open Toolkit. Recently I've noticed that I forgot to implement tgroup/@align attribute.

tgroup/align="left" will be mapped <fo:table-and-caption text-align="left">. tgroup/align="right" will be mapped <fo:table-and-caption text-align="right">. And tgroup/align="center" will be mapped <fo:table-and-caption text-align="center">. However I'm not sure how to implement following two align attribute values.

justify:

DITA 1.2 specification says as following.

"Justifies the contents to both the left and the right."

As table is not the sentence it cannot be justified. Or should I take same implementation as table/@pgwide="1"?

char:

DITA 1.2 specification says as following.

"Use the character specified on the char attribute for alignment."

What char attribute should I adopt as alignment char? This attribute is defined in colspec or entry element. But it is not defined in tgroup element. Should I inherit it to entry element and use char attribute defined in entry element?

Any suggestions are welcome.

This was my interpretation mistake of DITA 1.2 specification.

3.1.1.3.2 tgroup

http://docs.oasis-open.org/dita/v1.2/os/spec/langref/tgroup.html#tgroup

"Describes the alignment of text in a table column. "

It is applied to "column text" not to table itself. So tgroup/@align should be inherited to entry element level or specified as fo:table/@text-align as the inheritable attribute in XSL-FO.

So I realized there is no attribute to align the table (fo:table-and-caption) itself in DITA specification.
