[xsd-users] Default values of elements that use enumerated types

[Tony McConnell]

Hello,

I'm using xsd amd64 4.0.0-1 debian package on Ubuntu 14.04 with xerces-c
3.1.1-5.1

I'm using the following to generate code for parsing and serialising:

xsdcxx cxx-tree --hxx-suffix .h --cxx-suffix .cc --reserved-name
xml_schema=datex2api_xml_schema --generate-serialization
--proprietary-license --generate-polymorphic --polymorphic-type-all
--disable-warning all --extern-xml-schema datex2_common.h
--polymorphic-plate 1 \
           --namespace-map
http://datex2.eu/schema/2_0RC2/2_0=datex2_0RC2_2_0
/tmp/DATEXIISchema_2_0RC2_2_0.xsd

The schema contains an enumerated type, PrecipitationType, based on
xsd:string and an element, precipitation, that uses that type. but which
also has a default value of 'drizzle'.

'<element name="precipitation" type="PrecipitationType" default="drizzle">'

When I create some XML that has '<precipitation>drizzle</precipitation>',
xmllint and the generated parsing code are happy with it.

When I create some XML that has '<precipitation></precipitation>', xmllint
is happy, but the generated code produces an 'unexpected enumeration'
exception.

Should XSD support default element values, or is this some problem with the
underlying xerces-c parser?

Cheers
