[thelist] "Cannot generate system identifier" error while validating

[Richard Davey]

Hi all,

I've been running a web page through the W3C MarkUp Validation Service
and have nailed all the errors bar one (which just happens to occur
460 times!) - but I'm stumped to know how to get around it.

When validating I get loads of:

Line X, column Y: cannot generate system identifier for general entity "f"
Line X, column Y: reference not terminated by REFC delimiter
Line X, column Y: reference to external entity in attribute value

The actual error comes from a hyperlink that passes a parameter on the
Querystring, like this:

1. Line 58, column 62: cannot generate system identifier for general entity "f"
  ...ef="xt/xt_apollo_mark_read.php?i=all&f=1" class="ApolloBoldLink">Mark all boa
                                          ^
2. Line 58, column 62: general entity "f" not defined and no default entity (explain...).
  ...ef="xt/xt_apollo_mark_read.php?i=all&f=1" class="ApolloBoldLink">Mark all boa

I'm using XHTML 1.0 Transitional and iso-8859-1. The "explain" links
don't explain a thing.

Does anyone know what needs to be done in order to get a Querystring
value like that through the validator?
