[NeXus-committee] suggestion: remove attribute 'index' from NXDL element <dim>

[Pete Jemian]

Perhaps it's the general documentation that did not keep up with changes 
in the meaning?  That happens.

In this case, the intention of index="0" is described (consistently) but 
this usage did not make it into the documentation for the "index" 
attribute of the "dim" element in nxdl.xsd.

Here is what that documentation says now:
					<xs:attribute name="value" type="nx:NX_CHAR">
						<xs:annotation>
							<xs:documentation>
								Integer length (number of values), or mnemonic symbol
								representing the length of this axis.
							</xs:documentation>
						</xs:annotation>
					</xs:attribute>

It needs this additional explanation to be added.
If you agree with this remark, can you please make that change?
