[NeXus-tech] XML and new attribute

[Eugen Wintersberger]

Hi folks 
  I have an interesting question about attributes and NXDL. As we
defined a whole bunch of new attributes during the last NAIC meeting I
was wondering how they will be represented in NXDL. Will they go in the
tag, for instance like 

<field name="phi" type="NX_FLOAT" depends_on="chi"
transformation_type="rotation" vector="0,1,0" offset="0,0,0">

</field>

or will we store them using the attribute tag 

<field name="phi" type="NX_FLOAT">
	<attribute name="depends_on" type="NX_CHAR">chi</attribute>
	<attribute name="transformation_type" type="NX_CHAR">rotation</attribute>
	<attribute name="vector" type="NX_FLOAT"> 0 1 0 </attribute>
	<attribute name="offset" type="NX_FLOAT"> 0 0 0 </attribute>
</field>

In the latter case we should also ask if we would have to use a
"dimensions" tag to denote that this is a vector instead of a scalar. 
The reason why I am asking is that I am currently adopting my XML to
Nexus/Nexus to XML toolchain and just now stumbled upon this problem. 

Myabe (as usual) I missed something in the documentation. Any advice?

best regards
  Eugen
