No, they are allowed by the syntax. They are not valid.
The path segments "." and "..", also known as dot-segments, are
defined for relative reference within the path name hierarchy. They
are intended for use at the beginning of a relative-path reference
(Section 4.2) for indicating relative position within the
hierarchical tree of names. This is similar to their role within
some operating systems' file directory structure to indicate the
current directory and parent directory, respectively. However,
unlike a file system, these dot-segments are only interpreted within
the URI path hierarchy and are removed as part of the resolution
process (Section 5.2).
It doesn't matter what is the result of processing

because those are not valid file URIs.
