Before updating to the latest version of ID, I would get an error each time I tried to use the <cs> tag to format a cross-reference. It wouldn't let me save the data.

Now it lets me save the data, but it just strips the tag out.

I have a character setting called Bold.

I defined a cross-reference format as:
<cs style="Bold"><fullPara /></cs> on page <pageNum />

I save it, and I click OK. Then I reopen the format page, and it says the following:
<fullPara /> on page <pageNum />

It's like the tag never existed. No matter what I try, the tag never saves. I can apply a character style to the entire cross-reference, but not half of it. It is all or nothing. I can make text changes to the tag like adding quotes without a problem.
