/** Create this driver's NDAttributeList (pAttributeList) by reading an XML file
* \param[in] fileName The name of the XML file to read.
*
* This clears any existing attributes from this drivers' NDAttributeList and then creates a new list
* based on the XML file. These attributes can then be associated with an NDArray by calling asynNDArrayDriver::getAttributes()
* passing it pNDArray->pAttributeList.
*
* The following simple example XML file illustrates the way that both PVAttribute and paramAttribute attributes are defined.
* <pre>
* <?xml version="1.0" standalone="no" ?>
* \<Attributes>
* \<Attribute name="AcquireTime" type="EPICS_PV" source="13SIM1:cam1:AcquireTime" dbrtype="DBR_NATIVE" description="Camera acquire time"/>
* \<Attribute name="CameraManufacturer" type="PARAM" source="MANUFACTURER" datatype="STRING" description="Camera manufacturer"/>
* \</Attributes>
* </pre>
* Each NDAttribute (currently either an PVAttribute or paramAttribute, but other types may be added in the future)
* is defined with an XML <b>Attribute</b> tag. For each attribute there are a number of XML attributes
* (unfortunately there are 2 meanings of attribute here: the NDAttribute and the XML attribute).
* XML attributes have the syntax name="value". The XML attribute names are case-sensitive and must be lower case, i.e. name="xxx", not NAME="xxx".
* The XML attribute values are specified by the XML Schema and are always uppercase for <b>datatype</b> and <b>dbrtype</b> attributes.
* The XML attribute names are listed here:
*
* <b>name</b> determines the name of the NDAttribute. It is required, must be unique, is case-insensitive,
* and must start with a letter. It can include only letters, numbers and underscore. (No whitespace or other punctuation.)
*
* <b>type</b> determines the type of the NDAttribute. "EPICS_PV" creates a PVAttribute, while "PARAM" creates a paramAttribute.
* The default is EPICS_PV if this XML attribute is absent.
*
* <b>source</b> determines the source of the NDAttribute. It is required. If type="EPICS_PV" then this is the name of the EPICS PV, which is
* case-sensitive. If type="PARAM" then this is the drvInfo string that is used in EPICS database files (e.g. ADBase.template) to identify
* this parameter.
*
* <b>dbrtype</b> determines the data type that will be used to read an EPICS_PV value with channel access. It can be one of the standard EPICS
* DBR types (e.g. "DBR_DOUBLE", "DBR_STRING", ...) or it can be the special type "DBR_NATIVE" which means to use the native channel access
* data type for this PV. The default is DBR_NATIVE if this XML attribute is absent. Always use uppercase.
*
* <b>datatype</b> determines the parameter data type for type="PARAM". It must match the actual data type in the driver or plugin
* parameter library, and must be "INT", "DOUBLE", or "STRING". The default is "INT" if this XML attribute is absent. Always use uppercase.
*
* <b>addr</b> determines the asyn addr (address) for type="PARAM". The default is 0 if the XML attribute is absent.
*
* <b>description</b> determines the description for this attribute. It is not required, and the default is a NULL string.
*
