Hi Roger,
Ah, I see now that it's not valid with respect to the schema.
ie. the problem with <tag/> is not that it's an illegal string, but that it's not a string at all.
<xsd:element
name="Author" type="xsd:string" />
<Author> <tag/>
</Author>
> However, that's not the same thing as giving Author a non-string value.
Being pedantic, I guess <tag/> is a "non-string" value.
PS: I think you meant "not valid", instead of "non-well-formed" - I always get those two confused, and had to look it up.

Hi Brendan,
I think that's an example of <Author> having
non-well-formed content, not an example of <Author> having an illegal
string value. Certainly if the "<" is escaped then <Author> is
legal:
<Author> <tag/>
</Author>
I'm not sure what the answer is.

Subject: Re:
Brain Teaser: Element Author is of type xsd:string, what's an illegal value of
Author?
What about
<Author> <tag/>
</Author>
Isn't an element a non-string value, and therefore
illegal?

<xsd:element

<?xml

<Book>
<Author>...</Author>
</Book>
Question:
what is an invalid (non-string) value for <Author>?
