Module elements/container

Renderer for "container" AST elements -- the most general wrapper node in the Wikidot AST.

A container can represent many different HTML constructs depending on its type discriminant:

• Headers (h1..h6) with optional TOC anchor IDs
• Text alignment wrappers (left, center, right, justify)
• Inline formatting (bold, italics, underline, strikethrough, superscript, subscript, monospace, mark, insertion, deletion)
• Block containers (paragraph, div, blockquote, span)
• Visibility modifiers (hidden, invisible)
• Ruby annotations (ruby, ruby-text)
• Definition lists (definition-list, definition-list-item, etc.)
• Table sub-elements (table-row, table-cell)
• Size containers with inline font-size styling

All attributes are sanitized before rendering to prevent XSS.
