plainleaf/website/Object/page.md

Every page in your space is available via the page tag. You can attach additional tags to a page, by either specifying them in the tags attribute Frontmatter, or by putting additional Tags in a stand alone paragraph with no other (textual) content in them.

In addition to ref and tags, the page tag defines a bunch of additional attributes as can be seen in this example query:

${query}

Note that you can also query this page using the level/intermediate directly: ${queryfrom index.tag "level/intermediate"}
