Hi,
I'm getting the following validation error with XMLspy when validating
an "xsd" file:
Schema Error: the group 'DateUnionGroup' is undefined
However, in the xsd document the group 'DateUnionGroup' IS defined.
This is an extract of the document
First, two groups are defined, "PeriodGroup" and "DateUnionGroup".
Afterwards, a record type called "StringRecType" is defined. The error
is generated by the line ...<xs:group ref="DateUnionGroup"/>...
Any ideas?
Many thanks
Max
