Why aren't topics with Dita 1.3 in the metadata coming across when I use ant to generate the html files from my .xml files created in Framemaker?

[jb61539814]

We have been creating documents under Dita 1.2 in FrameMaker and running ant to convert them to html files to create webhelp. I want to update to dita 1.3 as I want to use ResponsiveHTML5 help. But when I generate the help, any topics created with the Dita 1.3 setting in FrameMaker do not appear in my help output.

What am I missing?
