MinOccurrence/MaxOccurrence

["Michael Dill" <dill2@gefeg.com>]

Stephen,
in Amsterdam I gave and we discussed the EF generated draft schemas from the
UBL model. EF just generated MinOccurrence/MaxOccurrence if different from
the default. You said that MinOccurrence/MaxOccurrence shall occur in any
case. Now we changed as requested (for the EF generated schemas) BUT:

1. a sequence has MinOccurrence/MaxOccurrence as well. Neither your schemas
nor the handcrafted schemas ('Parameters'etc) use this. Thus we decided, not
to write any MinOccurrence/MaxOccurrence for a sequence. a) Correct? b) If
there is any rule in the NDR roolbook for this, then please let's make sure
that this issue is clearly stated in that rule, OK?

2. At least the handcrafted schemas ('Parameters' etc.) do not follow the
rule "MinOccurrence/MaxOccurrence shall occur in any case" you gave us.
Example: UBL-CoreComponentParameters-1.0-draft-4.xsd
shows "<xsd:complexType name="ComponentType">
		<xsd:sequence>
			<xsd:element ref="CategoryCode" minOccurs="0"/>"
and shows "<xsd:complexType name="ContextType">
		<xsd:sequence>
			<xsd:element ref="IndustryClassification" minOccurs="0"
maxOccurs="unbounded"/>"
conclusio: decision and rule in the NDR rulebook is needed, whether
MinOccurrence/MaxOccurrence has just to be exist, if there is any non
default value OR always.

Tim,
please correct me, if the above mentioned issue is already clear.
regards
Michael
