UNCONFIRMED  errors and comments from readers: 


{4} Example 1-6;
The right-hand side of the 'let' statement refers to 'named'. Should that be 'name'?

let $name := $product/named

vs.

let $name := $product/name


{5} Example 1-7;
To be correct HTML, shouldn't there be <li/> tags around each line item?


{28} variables paragraph 2;
Most implementations allow reuse of variable names without giving an error. For example eXist, saxon.


(38) Table 3-5;
There is an extra space in the path expression in the third row of the first column of Table 3-5. I think 
it should be:

not(doc("catalog.xml")/catalog/product)


{158} 3rd paragraph;
same heading as paragraph 4 of page 158
Suggestion: Casting from xs:string or xs:untypedAtomic
