parameters for a xPico Wi-Fi embedded device server, or it may only change the baud rate for a
single serial line. Using XCRs is a straightforward and flexible way to manage the configuration of
multiple XPico Wi-Fi embedded device servers.

XML Configuration Record Document Type Definition
An XML document type definition (DTD) is a description of the structure and content of an XML
document. It verifies that a document is valid. XCRs are exported using the DTD as shown in
Figure A-3 DTD for XCRs
.

<!DOCTYPE configrecord [
<!ELEMENT configrecord (conf)>
<!ELEMENT configgroup (con,configgroup*)>
<!ELEMENT configitem (value+)>

The xPico Wi-Fi DTD rules state the following:
The XML document element is a
<configrecord>
element. This is the root element.
A
<configrecord>
must have one or more
<configgroup>
elements and can have a
version attribute.
A
<configgroup>
must have one or more
<configitem>
elements and can have name
and instance attributes.
A
<configitem>
element must have one or more <value> elements and can have a name
attribute.
A
<value>
element can have only data and can have a name attribute.
The name attribute identifies a group, item, or value. It is always a quoted string.
The instance attribute identifies the specific option, like the serial port number. The "instance"
attribute is always a quoted string.
Note:
The name for each <configgroup> (specified with the name attribute) is the group
name listed in the Web Manager XCR groups or with the "xcr list" CLI command. See
the xPico Wi-Fi Embedded Device Server User Guide for more information about the
XCR groups.
