You can also mix block quotes with paragraphs and other block wikitext. Be mindful of block mode - if other quoted content follows a paragraph, end it with a blank line. The final paragraph in the quote does not need to end with a blank line. If using indentation, make sure __not to indent the blank lines__. The parser will interpret this as additional inline content and not return to block mode. For example:
<<wikitext-example src:'<<< Mixing Block Quotes with Inline Wikitext
A paragraph appears before other //wikitext//, which needs to end with a blank line.

<<<< Deep Block Quote

!! Sub Header
