Some of the plantuml diagrams in the I/O storage abstraction layer documentation are absent from the rendered version of the porting guide. The build log (see [1] for example) reports a syntax error in these files. This is due to the usage of the 'order' keyword on the participants list, which does not seem to be supported by the version of plantuml installed on the ReadTheDocs server. Fix these syntax errors by removing the 'order' keyword altogether. We simply rely on the participants being declared in the desired order, which will be the order of display, according to the plantuml documentation.
