clarification of @uref{#label} requested

[Richard Y. Kim]

In texinfo 4.0 manual info node "(texinfo)uref", the `@uref' command
is described.  However it is not clear if one can use URL to another
place of the same document, e.g.,


  @anchor{label}
  ...
  @uref{#label}

A comment on whether or not this is legal would be appreciated.
Also, is this legal?

  @node nodename
  ...
  @uref{#nodename}

Thanks.
