Hi Roger,
For this case, some form of static error reporting is already
defined in the XPath 2.0 spec. Please see:
http://www.w3.org/TR/xpath20/#id-schema-element-test
<quote>
schema-element(ElementName)
If the ElementName specified in the SchemaElementTest is not found in
the in-scope element declarations, a static error is raised
[err:XPST0008].
</quote>
But your suggestion to ask for a better error reporting looks good to
me (as implemented by Saxon).

It may be that you think that the expression should be in error, but
in
that case your complaint should be with the XSLT Working Group who
specified it
Thanks David. You're right. Okay, I just sent the below message to

[XPath] Request XPath implementations be required to do some static
type checking on the schema-element function
Hi Folks,
I would like to request a small change to the XPath 2.0 specification.
I would like to request that XPath implementations be required to
generate an error or warning message for expressions like this:
schema-element(Book)/Foo
where Foo is not a valid child of Book, according to the in-scope
schema.
Further, implementations be required to generate an error or warning
message for expressions like this:
schema-element(Book)/Author/FirstNam
where, according to the in-scope schema, Author is a valid child of
Book but FirstNam (note that I misspelled Name) is not.
Thank you very much for your consideration.
