Spec: confused in "links" and "raw html

Reading the spec of Commonmark, I noticed the following:

  • HTML: Compare 4.6 and 6.8, specifically, the list of tags in 4.8 and this statement:

    > Text between < and > that looks like an HTML tag is parsed as a raw HTML tag and will be rendered in HTML without escaping.

  • Links: In the second definition of links destination:

    anonempty sequence of characters that does not include ASCII space or control characters, and includes parentheses only if (a) they are backslash-escaped or (b) they are part of a balanced pair of unescaped parentheses that is not itself inside a balanced pair of unescaped paretheses.

Does this mean that link destinations can be without parenthesis?

P. S.: Is this issue with blockquotes a bug or am I doing something wrong?

Probably just a bug in combining BBCode and Markdown. I edited your post to use just Markdown.

It is also a bad idea to use raw < and > without pre or escaping as HTML is supported in Markdown…
