I have a question about the following text in the 'Xml Schema Part 1'
regarding schema attribute declarations:

---
Attribute Declaration Representation OK:
...
2 If default and use are both present, use must have the *actual value*
optional.
---

Does the same rule apply to fixed values? There is no similar constraint
for that. 
Is the following attribute declaration allowed? If it is, what should be
the behavior during instance validation?

<xs:attribute name="att" use="required" fixed="37" />

Thanks,
Zafar
