How about having:

  <xsl:variable name="maxOccurs" select="(@maxOccurs,1)[1]"/>
... and then changing your tests to variables instead of attributes? You won't need the tests for absence since the variable assignment has accommodated absence.
I don't recognize what this is doing, I'm assuming it assigns 1 when not there, but I don't understand the syntax.

In XSLT 2 the expression (x,y)[1] will take the first member of the sequence of items addressed by "x" and then "y". A sequence does not contain any empty sets, so if "x" does not address anything then "y" is the first member of the sequence.

I suppose if there had been a DTD to validate against I could have checked for the value directly.

No, because the document model cannot be inspected by an XSLT stylesheet.

I hope this helps.
