| * | ||
| * Also, custom tags can come from the kdoc itself, where "custom" is defined as unknown to the compiler/spec. | ||
| * `@property` and `@throws` are not custom tags - they are defined by the spec and have special meaning | ||
| * and separate blocks on the documentation page, it's clear how to render it. Whereas `@usesMathJax` is | ||
| * a custom tag - it's application/plugin specific and is not handled by dokka by default. | ||
| * | ||
| * Using this provider, we can map custom tags (such as `@usesMathJax`) and generate content for it that | ||
| * will be displayed on the pages. | ||
