I registered some custom metadata fields in local-types.xml. Some of them
have character underscore '_' like this:
<dc-type>
<schema>local</schema>
*<element>conference_language</element>*
<qualifier>en</qualifier>
<scope_note></scope_note>
</dc-type>
I used this element in a custom submission form:
<row>
<field>
<dc-schema>local</dc-schema>
*<dc-element>conference_language</dc-element>*
<dc-qualifier>en</dc-qualifier>
<label>Conference language</label>
<input-type>onebox</input-type>
<hint>Enter the conference language.</hint>
<required>You must enter the conference language.</required>
</field>
</row>
DSpace throwed a exception when saving the form:

DSpace converted the character underscore in <dc-element> to character
period.
Does DSpace restrict special characters in definition of customized
metadata elements in local-types.xml?
Please suggest the specifications for defining customized metadata elements.
Thanks
