Description

Given the following xsd that should allow only a valid email address pattern:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<xsd:element name="Email" type="EmailType" />

<xsd:simpleType name="EmailType" >
<xsd:restriction base="xsd:token">
<xsd:pattern value="([\.a-zA-Z0-9_-])@([a-zA-Z0-9_-])(([a-zA-Z0-9_-])*\.([a-zA-Z0-9_-]))"/>
</xsd:restriction>
</xsd:simpleType>

</xsd:schema>

Using the following simple xml instance:

<Email>[e-mail]</Email>

Running:

validate sample.xsd sample.xml

generates:

Schema invalid:
D:\sample.xsd:7: error: pattern-regex: The regular expression '([\.a-zA-Z0-9_-])@([a-zA-Z0-9_-])(([a-zA-Z0-9_-])*\.([a-zA-Z0-9_-]))' is malformed: '-' is an invalid character range. Write '-'.

Question: Why should I have to escape the dashes??

Then escaping the dashes, you can actually get the schema to compile. But then you have a new problem. The regex does validate valid email addresses!!

So two bugs AFAIK - shouldn't need to escape slashes. Something in the regex is not recognised by xmlbeans regex parser.
