Thanks. Another problematic example is
Example 9.30. Folded Lines:

>
.folded
.line

.next
.line

...* bullet
...* list

.last
.line

# Comment

It is interpreted as

%YAML 1.1
---
!!seq [
    !!str "folded line\n\
    next line\n\
    \  * bullet\n\
    \  * list\n\
    last line\n"
]

So that a single line break between the lines.

    .line

and
    ...* bullet

It means that the line break after ".line" is folded. But the spec says

    ...empty lines separating lines of a different type are never
    folded...

By different types it seems to mean lines starting with a space and
lines starting with a non-space character.

As far as I understand the productions, folding may happen only between
lines starting with non-space characters.

In this case, the correct interpretation should be

%YAML 1.1
---
!!seq [
    !!str "folded line\n\
    next line\n\n\
    \  * bullet\n\
    \  * list\n\n\
    last line\n"
]

Is there an easy rule that describes how folding should be done?
