[ZPT] discrepency in TALES spec

[Fergal Daly]

The TALES wiki and the Zope book both say

--------
A path expression consists of one or more paths separated by vertical bar=
s=20
(|). A path consists of one or more non-empty strings separated by slashe=
s.=20
The first string must be a variable name (built-in variable or a user def=
ined=20
variable), and the remaining strings, the path segments, may contain lett=
ers,=20
digits, spaces, and the punctuation characters underscore, dash, period,=20
comma, and tilde.
-------

This means that=20

string:Anonymous Coward

is not a legal Path, so

request/name | string:Anonymous Coward

is not a legal Path Expression.

One way to fix this is to define an expression as

Expression: expr_segment [ '|' expr_segment ]*

where expression segment is any of path expression, string expression, no=
t=20
expression, etc.

Is this the way it works anyway?

By the way, I tried to post this as a comment on

http://www.zope.org/Documentation/Books/ZopeBook/current/AppendixC.stx

but I got a screenful of HTML source code which mentioned something about=
me=20
not being logged in, even though I was,
