I have included my minimal Markdown file, minimal json bibliography and the CSL file.

The problem: I cannot get book titles to appear in title case.

The relevant line in the CSL file would seem to be line 90.

• If I set text-case="uppercase" in line 90, then the book titles appear as UPPERCASE in both citation and bibliography.

• If I set text-case="lowercase" in line 90, then the book titles appear as lowercase in both citation and bibliography.

Those experiments suggest to me that line 90 is indeed the relevant line for setting book title case.

However, if I set text-case="title" in line 90, then the book titles appear in "capitalize-first" case.

But, again, as in my original post, if I insert the citation directly in LibreOffice using the Zotero plugin, the titles appear correctly, in title-case.

The issue only comes up when using pandoc for conversion.

If the issue is, as Denis suggests, something to do with nesting / precedence, I would be grateful is someone could point out where my CSL file is creating that conflict. I have tried to find something but without any success.

But it seems odd to me if that is the case that I *can* set the titles to "uppercase" and "lowercase" but *not* to "title" case when changing the same line.

And, again, this only arises with pandoc conversion.

So is this something I can change in my CSL? Or is this a pandoc issue?

Good catch. I'll open an issue on the CSL schema repo. But concerning precedence have a look at https://docs.citationstyles.org/en/stable/specification.html#inheritable-name-options where you'll find:

> When an inheritable name attribute is set on cs:style, cs:citation or cs:bibliography, its value is used for all cs:names elements within the scope of the element carrying the attribute. If an attribute is set on multiple hierarchical levels, the value set at the lowest level is used.

That's about inheritable name attributes, sure. But I'd infer from that that there seems to be a preference for settings at lower levels.
Maybe we should prohibit the use of styles and text-casing with macros as these run somewhat against the purpose of macros...
