Punctuation - 書名號 in writing a title and chapter of a documentation
GB/T 15834-2011, Section 4.14.3.2 seems to be more relevant than the section cowboy referenced since it explicitly mentions chapters in addition to volumes:

标示书名与篇（章、卷）名之间的分界。
示例： 《淮南子·本经训》

In other words, a middle dot should be used between the title and chapter. As others have noted, the Taiwanese reference describes the middle dot character but is using an ideographic full stop AKA period character which is not semantically equivalent to a middle dot.
There is no full-width middle dot character in Unicode and you're expected to achieve that effect using fonts and glyph selection tools such as CSS' relatively new font-variant-east-asian property. That's easier said than done though since you first need to find a font that provides a full-width middle dot glyph and the only one I know of is Adobe Ming Std.
Also, if you have a chapter/section number, one example I've seen of that kind of labeling is at http://www.certifiedchinesetranslation.com/openaccess/rdfconcepts-tc.html#section-Literals where a section title is labeled in the form of &quot;第4節Early Uniform Normalization&quot;. Of course, you can use 章 in lieu of 節 for both chapters and sections.
