XPath bug (typo ?) in oscal_catalog_metaschema.xml

[iMichaela]

Describe the bug

Per the XPath tutorial, chapter Selecting nodes:

Expression	Description
nodename	Selects all nodes with the name "nodename"
/	Selects from the root node
//	Selects nodes in the document from the current node that match the selection no matter where they are
.	Selects the current node
..	Selects the parent of the current node
@	Selects attributes

the following XPath are indicating a selection of the part, andprop respectively from the root and not from the current node (part ) when related to the assessment-methods of a control statement. I believe the intention was for the Path to represent a selection from the current node since an assessment-method is defined in the context of a control statement :

Line number	Current Path	Corrected Path
285	part[has-oscal-namespace('http://csrc.nist.gov/ns/oscal') and @name=('assessment','assessment-method')]/part[has-oscal-namespace('http://csrc.nist.gov/ns/oscal')]/@name	part[has-oscal-namespace('http://csrc.nist.gov/ns/oscal') and @name=('assessment','assessment-method')]//part[has-oscal-namespace('http://csrc.nist.gov/ns/oscal')]/@name
