Required filed

[Carlos]

Hello everybody,

I have doubt, why is it required ('Cannot be blank') a field when is added
to the schema as base64Binay or Datetime?

here you have an example of my schema

Any suggestions will be apreciated,
Thanks, Carlos

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema targetNamespace="http://tempuri.org/XMLSchema.xsd"
elementFormDefault="qualified"
xmlns="http://tempuri.org/XMLSchema.xsd"
xmlns:mstns="http://tempuri.org/XMLSchema.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Employee">
<xs:complexType>
<xs:sequence>
<xs:element name="FirstName" type="xs:string" />
<xs:element name="LastName" type="xs:base64Binary" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

Is this a custom XSD built outside infopath?

Thanks, yes it is, and I can show you another one made by Visual Studio
following an infopath lab where happens the same:

Regarding my last post, minoccurs=0 for the element in the fields list seemed
to fix this.

Carlos,

Try a something like this...
