[cxml-devel] RNG question

[Cyrus Harmon]

So I'm trying to parse a schema that has the following in it:

property-attach = element attach {

    element parameters {
        fmttypeparam? &
        encodingparam?
    }?,

    value-uri | value-binary
}

In order to get this to work with cxml-rng, I have to do the following:

property-attach = element attach {

    element parameters {
        fmttypeparam? &
        encodingparam?
    }?,

    ( value-uri | value-text )
}

Is the former invalid RNC or is cxml-rng's parser barfing where it shouldn't? A complete, minimal-ish example is shown below and attempting to parse it gives:

                                                                               :INCLUDE
                                                                               CXML-RNG::IDENTIFIER

                                                                               :DIV
                                                                               CXML-RNG::|)|
                                                                               CXML-RNG::CNAME
                                                                               CXML-RNG::|,|)
